Abstract
A picture-frame size of a display device including self light-emitting type display elements which are driven by a current is reduced over conventional devices. Transistors for controlling supply of a light-emission enable signal outputted from an emission driver to emission lines are provided between the emission driver and the emission lines. In such a configuration, based on selection signals provided to the transistors, one of the transistors is brought into an on state in each subframe, and each of the transistors is brought into an on state once during one frame period.
