Abstract:
1. A display device comprising: a plurality of signal lines which inputs a video signal to pixels each of which has a light emitting element; and a drive circuit which supplies the video signal and a PWM signal to the signal lines, wherein each pixel includes a drive transistor which drives the light emitting element based on the video signal, a capacitive element which is arranged between the signal line and a control electrode of the drive transistor, and a reset switching element which is arranged between the control electrode and a second electrode of the drive transistor, one frame period includes a writing period in which the video signal is written in the pixel, and a light emission period in which the light emitting element emits light, within the light emission period, the reset switching element is turned off and the PWM signal is supplied to the signal line from the drive circuit, and a cycle of the PWM signal in a low brightness display mode is shorter than a cycle of the PWM signal in a standard brightness display mode.
