Abstract: A display device including a base layer, a circuit layer including 1-1 and 1-2 pixel circuits, and a light emitting element layer including first and second light emitting elements each including a first electrode, an emission layer, a second electrode, and a pixel defining film. The 1-1 pixel circuit and the 1-2 pixel circuit each include a driving and a gate conductive layer. An area in which the first electrode of the first light emitting element overlaps the gate conductive layer of the 1-1 pixel circuit in plan view is equal to an area in which the first electrode of the second light emitting element overlaps the gate conductive layer of the 1-2 pixel circuit in plan view.

Abstract: A display device includes: pixel circuits defining pixel circuit rows each extending in a first direction and pixel circuit columns each extending in a second direction crossing the first direction; active patterns disposed to correspond to the pixel circuits, respectively; a horizontal diode initialization voltage line which transmits a diode initialization voltage and extends in the first direction; and a vertical diode initialization voltage line extending in the second direction and connected to the horizontal diode initialization voltage line. Each of the active patterns includes first and second diode initialization active regions to which the diode initialization voltage is applied. First active patterns of the plurality of the active patterns corresponding to one of the pixel circuit rows are connected to each other. A first end of one of the first and second diode initialization active regions contact the vertical diode initialization voltage line.
