Abstract:
1. A display device, comprising for each pixel: a photo-emission element and a first MOS transistor connected in series between a first power source line and a second power source line; a capacitor connected between a gate and a source of the first MOS transistor; and a second MOS transistor connected between a signal line and the gate of the first MOS transistor, the second MOS transistor being controlled by a scan signal that changes between an ON-state and an OFF-state, wherein an ON-period of the first MOS transistor is established within a period in which the photo-emission element is maintained to a non-light emission state and the signal line is applied with a voltage having a fixed level independent from an image signal voltage that is otherwise applied to an image signal line, and wherein the ON-period of the first MOS transistor is provided by raising a voltage of the scan signal from Voff to Von and then lowering the voltage of the scan signal from Von to Voff.
