Abstract
The present invention provides a liquid crystal display device including a multiple primary color panel capable of improving the display quality in the vicinity of a monochromatic color, and a control method therefor. The present invention provides a liquid crystal display device that performs display by input thereto of image signals for three colors from outside. The liquid crystal display device includes a liquid crystal display panel and a backlight. A plurality of pixels each including picture elements of four colors or more are formed in a display region of the liquid crystal display panel. Each pixel includes picture elements of three colors, provided with color filters having colors corresponding to the respective colors of the image signals, and at least one picture element of other color(s), provided with a color filter having a color corresponding to a color other than the colors of the image signals. The light emission intensity of the backlight can be controlled in accordance with image signals input. The light emission intensity of the backlight when a monochromatic color or a color close to a monochromatic color is displayed in the display region is greater than the …
