Image display device
Abstract:
In an image display device, a transistor formed in each pixel circuit is an N-channel transistor. Each pixel circuit further comprises an enable switch disposed in a current path supplying electric current to a light-emitting element and a supplementary capacitor for controlling changes in voltage of a terminal of a holding capacitor at one end opposite another terminal connected with writing switch. The light-emitting element is connected between the source of a driver transistor for supplying a current to the light-emitting element and a low-voltage side power line, an enable switch is connected between the drain of the driver transistor and a high-voltage side power line, and supplementary capacitor is connected between the drain of driver transistor and a predetermined power line.
