Abstract:
1. A display device, comprising: a two-dimensional array of a plurality of display pixels each having a display element layer and a drive circuit layer stacked, the drive circuit layer being for driving the display element layer, wherein the drive circuit layer includes a parallel-plate capacitor unit having a first electrode layer, a second electrode layer, a third electrode layer, and a plurality of insulating layers, the first electrode layer and the second electrode layer being arranged opposite to each other in a stacking direction, the third electrode layer being formed in a region other than a region interposed between the first electrode layer and the second electrode layer and being arranged opposite to the first electrode layer or the second electrode layer in the stacking direction, and the insulating layers being provided between the first electrode layer, the second electrode layer, and the third electrode layer, the parallel-plate capacitor unit includes: a capacitor element having a first capacitor electrode, a second capacitor electrode, and one of the insulating layers, the first capacitor electrode being electrically connected to a first line and provided in the first electrode layer, the second capacitor electrode being electrically connected to a second line and provided in the second electrode layer opposite to the first capacitor electrode in the stacking direction; a backup capacitor electrode positioned opposite to the first capacitor electrode or the second capacitor electrode in the stacking direction and provided in the third electrode layer, the backup capacitor electrode not being electrically connected to any of the first line, the second line, the first capacitor electrode, and the second capacitor electrode before a repair; a disconnect-able portion at which an electric connection between the first capacitor electrode and the first line can be disconnected; and a connectable portion at which the backup capacitor electrode and the first line can be electrically connected in the repair, and the disconnect-able portion and the connectable portion are arranged at a position in which the disconnect-able portion and the connectable portion overlap in the stacking direction.
