Abstract
A light-emitting apparatus comprising pixels that each includes a light-emitting element and a drive transistor for supplying a current according to a luminance signal to the light-emitting element and a signal supply circuit supplying the luminance signal to the drive transistor. The apparatus operates display modes including a first display mode and a second display mode in which a maximum luminance is higher than in the first display mode. The signal supply circuit, in a case where the display data has a maximum luminance value, supplies to the drive transistor, as the luminance signal, different voltages in the first and second display modes, and in a case where the display data has a minimum luminance value, supplies to the drive transistor, as the luminance signal, different voltages in the first and second display modes.
