Abstract
A display device includes: a light source section having multiple light sources to emit light in illumination colors including three primary colors of light; a display section for displaying an image in monochrome color by modulating the light emitted from the light source section; and a display control section for driving the light source section and the display section in a field sequential system. The display control section includes a determining section for determining a degree of white or a degree of complementary color of the light sources on the basis of an amount of lighting of each of the illumination colors of the light sources, a setting section for setting white components or complementary-color components of a color determined by a mixing ratio of the illumination colors, and an allocating section for allocating the set white components or the complementary-color components to the fields.
