A light emission intensity of the second sub-pixel is increased at a predetermined ratio with respect to a light emission intensity of the first sub-pixel when the first sub-pixel emits light at a light emission intensity within a low-luminance range equal to or lower than a predetermined level of luminance.

A display device includes: a display panel with pixels arranged in a first direction and a second direction; and a light source. Each pixel includes: a first sub-pixel including a color filter for a first color; and a second sub-pixel arranged adjacent to the first sub-pixel in the first direction and including a color filter for a complementary color between a second color and a third color. The light source includes: a first light emitter configured to emit light in the first color; a second light emitter configured to emit light in the second color; and a third light emitter configured to emit light in the third color. One frame period includes: a first light emission period of causing the first and second light emitters to emit light simultaneously; and a second light emission period of causing the first and third light emitters to emit light simultaneously.

According to an aspect, a display device includes: a display panel including a display area provided with a plurality of pixels; and a light source configured to emit light to the display panel. Writing periods and lighting periods are alternately provided in one frame period for at least one color. Each writing period is a period in which part of a pixel signal is written to a corresponding one of the pixels. Each lighting period is a period in which light is emitted to the pixel after a corresponding one of the writing periods. A light amount in at least one of the lighting periods is larger than a light amount in other lighting periods.
