Patent ID: 8563993

Claim:
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, and an insulating layer, the first electrode layer and the second electrode layer being arranged opposite to each other in a stacking direction, and the insulating layer being provided between the first electrode layer and the second electrode layer, the parallel-plate capacitor unit includes: a capacitor element having a first capacitor electrode and a second capacitor electrode, 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 element having a first backup capacitor electrode provided in the first electrode layer and a second backup capacitor electrode electrically connected to the first line and provided in the second electrode layer opposite to the first backup capacitor electrode in the stacking direction; a disconnect-able portion at which an electric connection between the second capacitor electrode and the second line can be disconnected; and a connectable portion at which the first backup capacitor electrode and the second line can be electrically connected, 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.
