Abstract
An image display device includes plural pixel circuits each of which includes a light emitting element where an amount of light emission changes corresponding to an amount of current and a drive transistor which controls the amount of current which flows to the light emitting element based on a display signal, a data line drive circuit which supplies a display signal to the plural pixel circuits respectively based on image data, a power source part which outputs a light-emitting potential, and a current amount prediction part which calculates an amount of current which flows to the plural pixel circuits from the power source part based on the image data. The power source part performs a control for suppressing fluctuation of the light-emitting potential based on the calculated amount of current and the outputted light-emitting potential.
