Abstract
A display device includes a plurality of pixel portions provided in a matrix form. Each of the pixel portions includes a pixel circuit and a light-emitting element. The pixel circuit includes a driving transistor connected between the light-emitting element and a first power supply line, a capacitor connected at its one end to a gate of the driving transistor, a switching transistor connected between the other end of the capacitor and a signal line, a threshold voltage detection transistor connected between a connecting point between the light-emitting element and the driving transistor, and a connecting point between the capacitor and the switching transistor, and a reset transistor connected between a connecting point between the driving transistor and the first power supply line, and a connecting point between the gate of the driving transistor and the capacitor, and connected at its gate to a reset control line.
