LIQUID CRYSTAL DISPLAY DEVICE
First Claim
1. A liquid crystal device comprising multiple pixels including first and second pixels that are arranged adjacent to each other,wherein each said pixel includes a number of subpixels including first, second and third subpixels, andwherein if an input signal indicates that each of the first and second pixels should represent a particular chromatic color, not only the third subpixel of at least one of the first and second pixels but also at least one of the respective first and second subpixels of the first and second pixels turn ON, andwherein if the average luminance of the respective third subpixels of the first and second pixels in one situation where the input signal indicates that each of the first and second pixels should represent the chromatic color is substantially equal to that of the respective third subpixels of the first and second pixels in another situation where the input signal indicates that each of the first and second pixels should represent an achromatic color, the luminances of the respective third subpixels of the first and second pixels in the former situation are different from those of the respective third subpixels of the first and second pixels in the latter situation.

Abstract
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.

11. A liquid crystal device comprising a pixel that has a number of subpixels including first, second and third subpixels,
wherein each of the first, second and third subpixels has a number of regions including first and second regions that are able to have mutually different luminances, and wherein if an input signal indicates that the pixel should represent a particular chromatic color, not only at least one of the first and second regions of the third subpixel but also at least one of the respective first and second regions of the first and second subpixels turn ON, and wherein if the average luminance of the first and second regions of the third subpixel in one situation where the input signal indicates that the pixel should represent the chromatic color is equal to that of the first and second regions of the third subpixel in another situation where the input signal indicates that the pixel should represent an achromatic color, the respective luminances of the first and second regions of the third subpixel in the former situation are different from those of the first and second regions of the third subpixel in the latter situation.
