Abstract
A display device includes a light source that emits a plurality of color lights, and a liquid crystal panel that controls transmission or reflection of the color light from the light source. One field is divided into a plurality of subfields: fr, fg and fb. A specific color light is emitted for at least a partial time of each subfield. An image corresponding to the specific color light is displayed on the liquid crystal panel. Durations of the subfields fr, fg and fb are set to be different from any other subfield in same field. A reflection-type gradation displaying is executed based on a combination of the durations of the subfields.
