Abstract:
A display device is provided that includes a plurality of pixels, each of which includes an electroluminescent (EL) element and a drive transistor that controls a current flowing through the EL element. The display device also includes a gate driver circuit that applies, to each of the plurality of pixels, a compensation voltage for compensating a threshold voltage of the drive transistor, in each of compensation voltage application periods included in a period other than a period in which a video signal voltage is applied. The display device further includes a control circuit that controls the gate driver circuit, wherein the control circuit adjusts a length of, among the compensation voltage application periods, a preceding compensation voltage application period immediately before the video signal voltage is applied.
