PURPOSE:To reduce the power consumption by increasing the utilization efficiency of a color light source and obtaining sufficient brightness even when the quantity of light of the color light source is decreased. CONSTITUTION:The color light source 6 is so driven and controlled as to emit red light, green light, and blue light in a one-frame period on a title-division basis and a liquid crystal panel 8 is so driven and controlled as to display a red image, a green image, and a blue image in the period wherein the red color is emitted by the color light source 6, the period wherein the green light is emitted, and the period wherein the blue light is emitted, erase the entire screen when the color light source switches the light emission colors, and switch the scanning direction at intervals of one frame.
