摘要： A liquid crystal display device (100) according to the present invention includes pixels (P1) and (P2), each of which includes three subpixels (R1, G1, B1) and (R2, G2, B2). When the input signal indicates that a chromatic color should be represented, one of the subpixels (B1 and B2) is turned ON and at least one of the subpixels (R1, R2, G1 and G2) is turned ON, too. If the average luminance of the subpixels (B1 and B2) in a situation where the input signal indicates that the chromatic color should be represented is substantially equal to that of the subpixels (B1 and B2) in another situation where the input signal indicates that an achromatic color should be represented, the luminances of those subpixels (B1 and B2) in the former situation are different from those of the subpixels (B1 and B2) in the latter situation.

摘要： 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.

摘要： Viewing angle characteristics on the entire display surface are improved while suppressing harmful effects such as flicker and banding caused by viewing angle improvement control. A liquid crystal display apparatus (1) includes: a liquid crystal panel (11) which includes a plurality of pixels arranged in a matrix; a drive control unit (24) which performs viewing angle improvement processing by converting a gradation of a video signal input to the pixel; and a processing object determination unit (22) which determines whether or not an image displayed on each of the pixels of the liquid crystal panel (11) is an image having an intermediate color. The drive control unit (24) is configured to perform the viewing angle improvement processing on the pixel determined by the processing object determination unit (22) such that the pixel displays the image having the intermediate color.

摘要： A liquid crystal device (100A) according to the present invention has first and second pixels (P1 and P2). Each of the first and second pixels (P1 and P2) includes first, second and third subpixels (R, G, and B). When the input signal indicates that each pixel should represent the first color, the luminances of the respective third subpixels (B1 and B2) of the first and second pixels (P1 and P2) are different from each other. But when the input signal indicates that each pixel should represent the second color, the average luminance of the respective third subpixels (B1 and B2) is substantially the same as when the first color is specified, and the luminances of the respective third subpixels (B1 and B2) are substantially equal to each other.
