A light-emitting element and a picture signal current supply circuit are formed near each of the crossings of scan lines and signal lines and a charging circuit is provided to precharge the electric capacitance of the light-emitting element with an electric load that is lower than the light-emitting threshold level of the element. With this arrangement, the time that needs to be spent before the light-emitting element, which is an organic EL element, starts emitting light is reduced so that it can be driven at high speed to display an image with tones.
