摘要： A display device uses a plurality of pixel circuits each of which includes a light-emitting element; a light-emission control switching element; a current control circuit for supplying a driving current, which corresponds to gray-level display data, to the light-emitting element via the light-emission control switching element; and a voltage control circuit, which includes a first capacitance element for storing a voltage corresponding to the gray-level display data, and controls ON/OFF operation of the light-emission switching element in accordance with the voltage stored. If the gray-level display data is data for causing the light-emitting element to display less than a certain luminance, the current control circuit supplies the light-emitting element with a constant driving current corresponding to the gray-level display data for displaying the certain luminance, and the voltage control circuit controls the ON time of the light-emission control switching element in accordance with a voltage stored.
