Abstract:
1. An image display device, comprising: a plurality of pixel scanning lines extending in a first direction; a plurality of signal lines extending in a second direction crossing the first direction; and a plurality of pixel circuits which are provided correspondingly to intersections between the plurality of pixel scanning lines and the plurality of signal lines and driven based on scanning signals supplied to the plurality of pixel scanning lines and image signals supplied to the plurality of signal lines, wherein each of the plurality of pixel circuits includes: wherein each of the plurality of pixel scanning lines connects directly to the pixel switch included in the corresponding one of the plurality of pixel circuits, and wherein each of the image signals comprises: a base potential which is predetermined and supplied for a first period of time longer than a time constant of the light emitting element; and an intensity potential which corresponds to an intensity of the light emitting element and is supplied for a second period of time shorter than the first period of time immediately after the base potential is supplied so as to correct an amount of current supplied by the driver transistor to suppress variation in the amount of current supplied by the driver transistor which variation is due to variation in threshold voltage of the driver transistor.
