Abstract: A display device includes: a gate transmission wiring; a gate insulating layer disposed on the gate transmission wiring; and a pixel electrode and a data transmission wiring that are disposed on the gate insulating layer. When a gate signal voltage is applied to the gate transmission wiring, the gate transmission wiring may serve as a gate electrode that activates a semiconductor layer. In addition, when such a gate signal voltage is not applied thereto, the gate transmission wiring may form an electric field by a voltage difference between the gate transmission wiring and the pixel electrode, to thereby control a liquid crystal layer.

Abstract: A display device includes a substrate, a driving layer which is disposed on the substrate, and includes first driving circuit groups each including N first pixel driving circuits and photo pixels each including a photo driving circuit and a photo sensor electrically connected to the photo driving circuit. A display element layer is on the driving layer, and includes first display element groups each including N first display elements electrically connected to the respective N first pixel driving circuits. Minimum distances between first color display elements included in the first display elements in a first predetermined direction in a plan view, are substantially the same. A distance between two first pixel driving circuits adjacent to each other in a second predetermined direction with the photo pixel therebetween in the plan view is different from a distance between two first pixel driving circuits continuously disposed in the second predetermined direction.
