Abstract

A display device includes: a liquid crystal display panel including a liquid crystal between two substrates; and first, second, and third light sources emitting light in different colors. A light emission period includes a first light emission period is which luminance of the first light source is higher than luminance of the second and third light sources, and at least one of the second and third light sources emits light, a second light emission period in which the luminance of the second light source is higher than the luminance of the first and the third light sources, and at least one of the first and third light sources emits light, and a third light emission period in which the luminance of the third light source is higher than the luminance of the first and second light sources, and at least one of the first and second light sources emits light.

Claims5

Dependent claims

A display system comprising:

a display device that comprises
a liquid cry seal display panel in which a liquid crystal is sealed between two substrates facing each other, and
a first light source, a second light source, and a third light source configured to emit light in colors different from one another;
and
a control device configured to control the first to third light sources to emit light such that saturation of color obtained by causing the first to third light sources to emit light in a first light emission period is lower than saturation of color obtained by causing only the first light source to emit light,
saturation of color obtained by causing the first to third light sources to emit light in a second light emission period is lower than saturation of color obtained by causing only the second light source to emit light, and
saturation of color obtained by causing the first to third light sources to emit light in a third light emission period is lower than saturation of color obtained by causing only the third light source to emit light.
