Claim 10:
11. A method for manufacturing a display device, comprising the steps of:
forming a TFT layer onto a base substrate, the TFT layer including a plurality of pixel circuits; and
forming a light-emitting element layer onto the TFT layer, the light-emitting element layer including a plurality of light-emitting elements arranged in correspondence with the plurality of pixel circuits,
wherein each of the plurality of pixel circuits includes
a TFT including a semiconductor layer, a gate insulating film, and a gate electrode, the gate insulating film covering the semiconductor layer, the gate electrode being provided in a form of an island overlapping a part of the semiconductor layer in a plan view on the gate insulating film, and
a capacitor including the gate electrode, a first inorganic insulating film, and a capacitive electrode, the first inorganic insulating film being disposed on the gate electrode, the capacitive electrode overlapping the gate electrode in the plan view on the first inorganic insulating film,

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, and
the method comprises:
a step of short-circuit identification comprising identifying, from among the plurality of pixel circuits, a pixel circuit with the gate and capacitive electrodes developing a short-circuit, the identifying step being performed between the step of forming the TFT layer and the step of forming the light-emitting element layer; and
a correction step comprising laser-light irradiation around a portion of the short-circuit between the gate and capacitive electrodes in the identified pixel circuit, to separate, from the capacitive electrode, the portion of the short-circuit between the gate and capacitive electrodes, the correction step being performed between the step of forming the TFT layer and the step of forming the light-emitting element layer.
