Reflective decorative panel of the present invention is the light reflecting image representation device used for production of a wide range of decorative products, advertising signs, billboards, panels, etc. The panel has a module base structure with holding elements on which reflective elements are cantilever mounted. The base structure is made in the form of a plastic lattice framework with longitudinal and transversal bearing bars, and it includes coupling elements at sides of the framework for attachment with frameworks of other modules. The coupling elements are located on edge bars at four sides of the framework. The reflective decorative panel is used for decoration of any kind of outdoor festive events, stage or TV design and facilities, where high strength and reliability of the modules attachment is of great importance.

An imaging device or a display device that is capable of clearly capturing an image of a fingerprint or the like can be provided. The display device includes a light-receiving element, a light-emitting element, a first substrate, a second substrate, a first resin layer, a second resin layer, and a light-blocking layer. The first resin layer, the second resin layer, and the second substrate are stacked over the first substrate. The light-receiving element and the light-emitting element are positioned between the first substrate and the first resin layer. The light-blocking layer is positioned between the first resin layer and the second resin layer and includes an opening portion overlapping with the light-receiving element. The opening portion in the light-blocking layer is positioned on an inner side of a light-receiving region of the light-receiving element in a plan view, and the width of the opening portion is less than or equal to the width of the light-receiving region. The second substrate is thicker than the first resin layer and the second resin layer. The thickness of a portion of the first resin layer, which overlaps with the light-receiving region of the light-receiving element, is greater than or equal to one time and less than or equal to 10 times as large as the width of the light-receiving region. The second substrate has a higher refractive index than the first resin layer and the second resin layer.

A novel display panel that is highly convenient or reliable is provided. A novel display device is provided. The display panel includes a display region, a first terminal region, and a second terminal region, and the first terminal region is provided not to block the display region and includes a region overlapping with the display region. The first terminal region includes a first group of terminals, and the first group of terminals includes a first terminal. The second terminal region includes a second group of terminals, and the second group of terminals includes a second terminal. The display region includes one group of pixels, another group of pixels, a scan line, and a signal line. The one group of pixels includes a pixel and is arranged in a row direction. The another group of pixels includes the pixel and is arranged in a column direction intersecting the row direction. The scan line is electrically connected to the one group of pixels. The signal line is electrically connected to the another group of pixels, and the signal line is electrically connected to the first terminal and the second terminal.

A connecting system of a multi-section housing provided at one end face of a first and second housing superposed with their display surfaces at the outsides, comprising: a first shaft vertical to superposed surfaces of first and second housing; and a second shaft perpendicular to the first shaft, wherein if a center line of the first shaft is arranged on a line bisecting the end face to the left and right and the center line of the second shaft is arranged on the superposed surfaces of the first and second housing, the first shaft can be used to allow the second housing superposed over the first housing to be rotated by 180 degrees and, in this state, the first housing can be made to rotate by the second shaft by 180 degrees so as to arrange the display surfaces of the first and second housings on the same plane.

A display device includes a substrate including a first surface, a plurality of pixel units on the first surface, and a first side wiring pad located in a first outermost array adjacent to a first side on the first surface and located between adjacent pixel units of the plurality of pixel units in a direction along the first side. A plurality of pixel units in the first outermost array can be arranged in a portion adjacent to an edge on the first surface of the substrate. A joint pixel pitch can thus be easily equalized to a non-joint pixel pitch, although the non-joint pixel pitch is smaller.
