Abstract
The present invention causes an oblique line to be smoothly displayed on a liquid crystal display device in which pixels are each constituted by subpixels of four colors arranged in a matrix with two rows and two columns. When the oblique line is displayed, pixels include: a pixel which is not in contact with the oblique edge; and a pixel which is in contact with the oblique edge, supplied with the same data as is supplied to the pixel and different in luminance of a subpixel from the pixel, The pixel having a higher luminance than those of pixels adjacent to the subpixel of the pixel, and the subpixel of the pixel having a lower luminance than that of the subpixel of the pixel.
Claims8
A liquid crystal display device in which each pixel is constituted by first-color to fourth-color subpixels arranged in a matrix with two rows and two columns, wherein:
- when an object having an oblique edge is displayed, (i) a first pixel on which the oblique edge does not fall and (ii) a second pixel (a) on which the oblique edge falls, (b) which is supplied with data identical to that supplied to the first pixel, and (c) in which the first-color subpixel has a different luminance from that of the first-color subpixel of the first pixel are in the liquid crystal display device;
- the second pixel has a higher luminance than those of pixels adjacent to the first-color subpixel of the second pixel;
- and
- the first-color subpixel of the second pixel has a lower luminance than that of the first-color subpixel of the first pixel.
