[0085] The diffusion plate 163 may have a lens function so that light emitted from the plurality of LED light sources 162 faces an outer periphery of the transmittance-variable panel 150 as indicated by arrows in FIG. 10.

[0086] The power supply member 170 configured to supply power to the light-emitting member 160 will be described with reference to FIGS. 12 and 13.

[0087] FIG. 12 is a perspective view illustrating a structure of the power supply member shown in FIG. 9, and FIG. 13 is a perspective view illustrating a structure of a first power supply member shown in FIG. 12.

[0088] As shown in FIGS. 9 and 12, the power supply member 170 includes a first power supply member 171 coupled to the hinge 110 and a second power supply member 172 coupled to the frame 120, and when the door 100 is closed, an electrical connection between the first power supply member 171 and the second power supply member 172 is formed, and when the door 100 is open, the electrical connection between the first power supply member 171 and the second power supply member 172 is cut off.

[0089] As shown in FIGS. 11 and 12, the first power supply member 171 includes a first protrusion 173 protruding from a first terminal, a first cable 176 electrically connected to the first terminal to receive power from the body, and a pair of coupling parts 178, and the first cable 176 is coupled to a connection jack 179.

[0090] The first terminal and the first protrusion 173 are provided to be electrically insulated from each other, and the first power supply member 171 is fastened to the hinge 110 by fitting the pair of coupling parts 178 into the coupling groove 114 provided in a body fixing part 112.

[0091] As shown in FIG. 12, the second power supply member 172 includes a second protrusion 174 protruding from a second terminal, a screw hole 175 provided to fix the second power supply member 172 to the frame 120 with a screw or the like, and a second cable 177 electrically connected to the first terminal to supply power to the light-emitting member 160. The second terminal and the second protrusion 174 are provided to be electrically insulated from each other, and power may be supplied to the light-emitting member 160 by the first protrusion 173 being brought into contact with the second terminal and the second protrusion 174 being brought into contact with the first terminal. That is, the first terminal is electrically insulated from the first protrusion 173 and electrically connected to the second protrusion 174. In addition, the second terminal is also electrically insulated from the second protrusion 174 and electrically connected to the first protrusion 173. The first protrusion 173 and the second protrusion 174 described above are provided to have, for example, functions of a positive (+) terminal and a negative (−) terminal.

[0092] As described above, by providing the first protrusion 173 to the first terminal and providing the second protrusion 174 to the second terminal, an electric shock may be prevented when in use, and the electrical connection state may be maintained even in the repetitive opening/closing operation of the door 100.

[0093] Thus, when the door 100 is opened from the body, the first protrusion 173 and the second protrusion 174 are spaced apart from each other so that the supply of power to the light-emitting member 160 is cut off, and when the door 100 is closed to the body, the first protrusion 173 and the second protrusion 174 are brought into contact with the first terminal and the second terminal, respectively, so that the voltage is maintained in a standby voltage state through the operation of the switching circuit.

[0094] Thereafter, when the user touches or taps the glass member 130, the movement detection member detects the movement, and information on the movement detection is transmitted to the light-emitting member 160 so that the switching circuit is turned on. Accordingly, when the plurality of LED light sources 162 emit light, since the amount of light between the transmittance-variable panel 150 and the protective panel 140 increases, an article inside the body can be confirmed from the outside through a plurality of nano-sized pores provided in the transmittance-variable panel 150. The light emission of the plurality of LED light sources 162 may operate only for a preset period of time with a timer configured to operate the switching circuit only for a predetermined period of time.

[0095] As described above, according to the present invention, since the plurality of LED light sources 162 emit light only for a preset period of time through the operation of the movement detection member and the timer, power consumption may be reduced.

[0096] Next, still another embodiment of the present invention will be described with reference to FIGS. 14 to 16.

[0098] In the embodiment described in FIGS. 10 and 11, the substrate 161 has a flat structure, and the plurality of LED light sources 162 are directed toward the outer periphery of the transmittance-variable panel 150, but as indicated by arrows in FIG. 14, the plurality of LED light sources 162 may be provided to face the inside of the body.

[0099] In addition, as shown in FIG. 15, the plurality of LED light sources 162 may be provided to face a transmittance-variable panel 150 by providing the substrate 161 in a trapezoidal shape. Thus, the installation of the light-emitting member 160 may be easily realized by applying the substrate 161 as shown in FIG. 15.

[0100] In addition, although the structure in which the movement detection member is provided on one side of the frame 120 has been described above, as shown in FIG. 16, a structure in which a movement detection member 180 is provided on an upper portion of the body 200 and causes the light-emitting member 160 to operate may also be applied. That is, a structure in which, when a user's movement, for example, the passing of a user's palm or the like, is detected by the movement detection member 180, the second power supply member 172 supplies power to the light-emitting member 160 may be provided.

[0101] Although the present invention has been described in detail with reference to the embodiments, it is to be understood that the present invention is not limited to the embodiments, and various modifications are possible to the extent that the gist of the invention is not deviated from.

[0102] That is, in the above description, as shown in FIG. 10, the structure in which the transmittance-variable panel 150 is mounted in a state parallel to the glass member 130 and LEDs of the light-emitting member 160 faces an edge of the transmittance-variable panel 150 is illustrated, but the present invention is not limited thereto, and the transmittance-variable panel 150 may be provided to be mounted obliquely with respect to the light-emitting member 160 so that light irradiated from the light-emitting member 160 passes through the glass member 130 through the plurality of nano-sized pores.

[0103] In addition, although the structure in which the first protrusion 173 is provided in the first terminal and the second protrusion 174 is provided in the second terminal has been described above, the present invention is not limited thereto, and a structure in which the first protrusion 173 and the second protrusion 174 are provided on either the first terminal or the second terminal may also be applied.

INDUSTRIAL APPLICABILITY

[0104] By using a storage box having a display panel according to the present invention, the amount of light incident from the outside is reduced, and the amount of light from a light-emitting member provided on the inside of a door is increased, so that an article inside a body can be confirmed from the outside.
