  • Patent number: 8879028
    Abstract: The LCD sequentially comprises, from bottom to top, a backlight module, a first polarizer, a first substrate, a liquid crystal layer, a second substrate, and a second polarizer. The second substrate comprises plural transparent areas thereon. The first substrate comprises plural light-focusing arrays. Each of the light-focusing arrays comprises plural high-refractive areas and low-refractive areas disposed between the high-refractive areas. The plural high-refractive areas comprises a first high-refractive area and plural second high-refractive area disposed on two sides of the high-refractive areas symmetrically, wherein the widths of the second high-refractive areas are the same and smaller than the width of the first high-refractive area.
