Abstract:
1. An image display device comprising: a display panel including a pixel circuit, the pixel circuit including a light-emitting element, a driver element, and a capacitor element, the light-emitting element emitting light when a voltage is applied thereto in a forward direction and accumulating electrical charge when a voltage is applied thereto in a reverse direction, the driver element causing the light-emitting element to emit the light when a voltage equal to or greater than a threshold voltage is applied thereto, the capacitor element accumulating electrical charge for adjusting current flowing in the driver element; a charge supply line for supplying electrical charge to the light-emitting element of the pixel circuit; and a drive control unit which supplies a second electrical charge from the charge supply line to the light-emitting element after a first electrical charge accumulated in the light-emitting element is supplied to the capacitor element, further supplies the second electrical charge to the capacitor element and accumulates the first electrical charge and the second electrical charge in the capacitor element, and applies a voltage greater than or equal to the threshold voltage to a control terminal of the driver element, within one frame after the light-emitting element emits light until the light-emitting element emits light next, wherein an amount of the second electrical charge is larger than an amount of the first electrical charge.
