Colour image display device, and colour image display method

Abstract

A field-sequential color image display device is provided which can sufficiently reduce power consumption while suppressing color breakup. In a liquid crystal display device that displays a color image under a field sequential system in which each frame period includes four field periods corresponding to three primary colors, namely red, green, and blue, and a white color, the emission intensity of a light source section () during the white field period is determined in advance so that the white color is displayed at a target maximum luminance when the transmittance of a pixel array section () is at its maximum during all of the four field periods. A drive control section () separates an input image signal into white, blue, green, and red components, expands the white component, and then assigns the components to the four field periods. This causes the pixel array section () to, during the respective field periods, display images of the corresponding colors based on the signal components thus assigned, giving a color image by an additive color mixture over time.
