An image display device is a self-luminous type device including a light emitting portion, and a casing portion of a display device unit has a heat dissipating structure portion through which a part of the image display device is exposed for heat dissipation. In manufacturing the display device unit, when performing simple and reliable assembly while securing a high heat dissipation characteristic, for example, by using characteristics of a silicon substrate, high accurate positioning is performed in a display device positioning portion.

A display device includes: a frame to be mounted on a head of an observer; and an image display device attached to the frame. The image display device includes: an image forming device; a light guide plate; a support substrate; a first deflection unit; a second deflection unit; and an optical member attached to the support substrate, in which light from the image forming device is deflected at the first deflection unit, propagated inside the light guide plate by total reflection, deflected at the second deflection unit, and incident on the optical member, and the optical member emits the incident light toward a pupil of an observer. The display device further includes a movement device that moves the support substrate with respect to the light guide plate in order to change a relative positional relation between the second deflection unit and the optical member.

A loudspeaker fixing structure and a display device are provided. The loudspeaker fixing structure includes: a fixing frame configured to be connected to a back plate of the display device; a pair of fixing side plates, opposite to each other and configured to be connected to a loudspeaker body; fixing members, fixed on the fixing frame and arranged in a one-to-one correspondence with the fixing side plates, and in each pair of the fixing side plate and the fixing member, the fixing member is at a side of one fixing side plate away from the other fixing side plate, the fixing member is fixed to the fixing side plate through a curved protrusion and a curved groove, and a protrusive direction of the curved protrusion is perpendicular to the fixing side plate.

[Problem] To propose a head-mounted display capable of restraining deformation or breakage of a connection member caused by concentration of an external force on the connection member. [Solution] A head-mounted display includes a frame worn on the head of a viewer and having a front part disposed in front of the viewer, and an image display device connected to a central part of the front part. The image display device includes two right and left optical modules each including an image generation device and a light guide member that is connected to the image generation device and is disposed closer as a whole to a center of the face of the viewer than the image generation device, and includes a connection member connecting the image display device to the front part. A part of the image display device is disposed so as to face a part of the front part in a front-rear direction with a predetermined gap interposed therebetween.

The present disclosure relates to a display apparatus in which a plurality of accommodation grooves in which a plurality of cables connected to a display unit is standardized and accommodated is formed on a rear surface of the display unit and the plurality of accommodation grooves has a length in the same direction as a plurality of patterns formed on the rear surface of the display unit.

The display apparatus includes a display unit in which a plurality of patterns having the same direction is formed on a rear surface thereof, a stand coupled to the display unit to support the display unit, a cable connection portion configured to connect a plurality of cables to the display unit, and accommodation grooves recessed on a rear surface of the display unit to have the same direction as the plurality of patterns and provided in a number corresponding to the plurality of cables such that the plurality of cables is accommodated therein, respectively.

A display apparatus includes a display panel, a back cover accommodating the display panel, and a sound output unit including at least one sound output module disposed to overlap the display panel. The at least one sound output module includes a support plate including an uneven surface and a piezoelectric element attached on the uneven surface of the support plate and has a shape corresponding to the uneven surface of the support plate. Accordingly, a sound having a straight characteristic within an audible frequency domain may be output, thereby enhancing a sense of reality and an immersion of a viewer watching an image displayed by the display apparatus.

A display device includes a display member, a lens, and a light intensity adjuster. The display member is configured to display an image by releasing relatively short-wavelength light and relatively long-wavelength light. The lens is configured to allow the image on the display member to be reproduced on an eye of the user and thicker in the middle thereof than at the periphery thereof. The light intensity adjuster is included in the display member. The light intensity is configured to allow short-wavelength light to be released from a middle of the display member in a larger amount than both short-wavelength light to be released from ends of the display member and long-wavelength light to be released from the middle of the display member.
