Abstract:
An image display device includes pixel circuits arranged in a matrix configuration between a first power supply line and a second power supply line. Each of the pixel circuits includes a light-emitting element and a first circuit connected to the light-emitting element and configured to set a duration during which a current is supplied to the light-emitting element based on a result of comparing a first signal and a first direct current voltage. The first signal includes a triangular wave signal. The first direct current voltage is set in a prescribed period. At least one of the pixel circuits includes a second circuit connected in series to the first circuit. The second circuit is configured to control a current supplied to the first circuit based on a second direct current voltage set in a period different from the prescribed period.
