Abstract:
A display device includes: a display portion including a plurality of pixel circuits arranged in a matrix; and a gate driver that outputs one driving pulse for each horizontal cycle. The plurality of pixel circuits each include subpixel circuits each including a light emitting element, a driving transistor that supplies a current to the light emitting element, a write transistor, a reference transistor, and an initialization transistor. The one driving pulse is input per vertical cycle from the gate driver to the initialization transistor included in each of a plurality of rows in the plurality of pixel circuits, and the one driving pulse input to the initialization transistors included in mutually different rows among the plurality of rows is input to each of the write transistor and the reference transistor, the mutually different rows being other than a row in which the write transistor and the reference transistor are included.
