Abstract:
A liquid crystal display device includes a liquid crystal display panel and a driving circuit that supplies display signals to a plurality of subpixels of the liquid crystal display panel. The plurality of subpixels are a red subpixel, a green subpixel, a blue subpixel, and a yellow subpixel. When achromatic colors of at least some gray levels among all gray levels are to be displayed by the pixel, display signals which are supplied to a first subpixel group composed of certain two subpixels are display signals of the same grayscale level, whereas display signals which are supplied to a second subpixel group composed of the other two subpixels are display signals of a different grayscale level from the grayscale level of the display signals supplied to the first subpixel group. The first subpixel group includes the yellow subpixel, and the second subpixel group includes the blue subpixel.
