Abstract
A display device includes: a base substrate; a TFT layer including a plurality of pixel circuits arranged; and a light-emitting element layer. Each of the plurality of pixel circuits includes: a TFT including a semiconductor layer, a gate insulating film, and a gate electrode; and a capacitor including the gate electrode, a first inorganic insulating film, and a capacitive electrode. The capacitive electrode extends all around a perimeter of the gate electrode and extends to an outside of the perimeter. An angle formed between an upper surface of the base substrate and at least a part of an end surface in a circumferential direction of the gate electrode not overlapping the semiconductor layer in the plan view is greater than an angle formed between the upper surface of the base substrate and an end surface of the gate electrode overlapping the semiconductor layer in the plan view.
