Pixel circuit and display device
Abstract:
A pixel circuit configured to emit light based on an image signal includes: a light emitting element (organic EL element); a driver transistor configured to adjust current supplied to the light emitting element; and a write transistor connected between a signal line to which the image signal is applied and the driver transistor. The driver transistor includes: a gate electrode; a counter electrode disposed opposite the gate electrode; and a channel disposed between the gate electrode and the counter electrode. A potential applied to the counter electrode in a write period in which the write transistor conducts current in a state in which the image signal is applied to the signal line reduces a resistance value of the driver transistor to lower value than a potential applied to the counter electrode in an emission period of the light emitting element does.
