Abstract:
1. A liquid crystal display device comprising 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, wherein each said 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, and wherein the area of the at least one bright subpixel is smaller than that of the at least one dark subpixel, and wherein if the at least one bright subpixel and the at least one dark subpixel are arranged in the Y direction in each said pixel, two closest pixels that belong to the same row to display the same color have geometric centroids with the same Y coordinate, the greatest difference between the Y coordinates of luminance centroids being equal to or smaller than a half of the length R wherein if the at least one bright subpixel and the at least one dark subpixel are arranged in the X direction in each said pixel, two pixels that are adjacent to each other in the column direction have geometric centroids with the same X coordinate, the greatest difference between the X coordinates of luminance centroids being equal to or smaller than a half of the length R wherein the luminance centroid of the at least one bright subpixel is different from the geometric centroid of the pixel.
