Abstract:
A display device includes: a plurality of light-emitting elements, each light-emitting element having a light-emitting unit and a driving circuit for driving the light-emitting unit. The driving circuit at least includes a drive transistor having source/drain regions, a channel forming region, and a gate electrode, a video signal write transistor having source/drain regions, a channel forming region, and a gate electrode, and a capacitive unit. In the drive transistor, one of the source/drain regions is connected to the corresponding current supply line, the other region of the source/drain regions is connected to the light-emitting unit and connected to one end of the capacitive unit, and forms a second node, and the gate electrode is connected to the other region of the source/drain regions of the video signal write transistor and connected to the other end of the capacitive unit, and forms a first node.
