Abstract
An electro-optical device includes a display panel, and an illumination device having a plurality of light sources emitting light of red, green, blue, and white. The illumination device is configured to illuminate the display panel by transmitting the light emitted from the plurality of light sources through the display panel. The chromaticity of a display screen of the display panel is adjusted to a predetermined chromaticity by changing the time for which each of the plurality of light sources is turned on within a time period of one frame.
