Abstract:
A liquid crystal display device includes a plurality of pixels that are arranged in matrix so as to form a plurality of rows extending in an X direction and a plurality of columns extending in a Y direction. Each pixel includes a liquid crystal layer and a plurality of electrodes for applying a voltage to the liquid crystal layer, and is split into at least one bright subpixel, which has a luminance higher than a certain luminance produced by a display signal voltage supplied, and at least one dark subpixel that has a lower luminance than the certain luminance. The area of the at least one bright subpixel is smaller than that of the at least one dark subpixel. If the at least one bright subpixel and the at least one dark subpixel are arranged in the Y direction in each pixel, two closest pixels that belong to the same row to display the same color have geometric centroids with mutually different Y coordinates. The greatest difference between the Y coordinates of luminance centroids is equal to or smaller than a half of the length RY of the two pixels as measured in the Y direction.
