Abstract
A display device includes a data signal line, a low-tone scanning line, a high-tone scanning line, a low-tone emission control line, a high-tone emission control line, a signal line drive circuit that outputs an image signal to the data signal line, a scanning line drive circuit that outputs a selection signal to the low-tone scanning line and to the high-tone scanning line, and first and second power supply lines that receive power from a power supply. Pixel units each include a low-tone scanning transistor, a high-tone scanning transistor, a low-tone capacitor, a high-tone capacitor, a low-tone drive transistor, a high-tone drive transistor, a low-tone emission control transistor, a high-tone emission control transistor, and a light emitter. The display device drives the light emitter by dividing a high tone and a low tone in time series.
