Abstract: A display device includes: a display panel including panel terminals; and a wiring substrate including first substrate terminals coupled to the panel terminals. The panel terminals include panel terminals arranged in a first region and panel terminals arranged in second regions sandwiching the first region. The first substrate terminals include first substrate terminals arranged in a third region and first substrate terminals arranged in fourth regions sandwiching the third region. A gap between panel terminals is substantially constant in the first and second regions. A first width of the panel terminals in the first region is different from a second width of the panel terminals in the second regions. A width of the first substrate terminals is substantially constant in the third and fourth regions. A first gap between first substrate terminals in the third region is different from a second gap between first substrate terminals in the fourth regions.

Abstract: In a display device which includes a display panel in which a plurality of pixels are arranged on a substrate two-dimensionally and which is configured to display an image therein, and a support member which supports the display panel, the support member possesses anisotropy in bending strength so as to encourage one-dimensional deformation (bending along only the X directional) of the display panel while suppressing two-dimensional deformation (bending in the X direction as well as the Y direction) of the display panel.

Abstract: A display device includes a plurality of pixels in matrix, a substrate on which the plurality of pixels are formed, and a support member under the substrate. The substrate is arranged on a front surface of the support member and a plurality of recesses are formed on a rear surface of the support member. Each of the substrate and the support member is formed in substantially rectangular shape and has a first side, a second side, a third side facing to the first side, and a fourth side facing to the second side. Each of the plurality of recesses extends in a first direction extending substantially in parallel to the first side and the third side.

Abstract: Terminal portions are arrayed at regular widths and regular intervals, and each face any enable terminal, and are electrically connected to the enable terminals by conductive particles. A lead portion is connected to the other terminal portion except for a pair of terminal portions which is a pair of terminal portions adjacent to each other, and extends from an overlap region to a lead region. A connection portion connects the respective terminal portions that are not connected with the lead portion to the adjacent terminal portions that are connected to the lead portion within an area of the overlap region. An interval between a pair of lead portions extending from a pair of connection portions located to sandwich a pair of terminal portions that are not connected with the lead portion therebetween is larger than an interval between the other adjacent lead portions.
