Patent ID: 8009251

Claim:
A high brightness liquid crystal display, the liquid crystal display comprising: a backlight module; a first polarizer on the backlight module; a first substrate on the first polarizer, wherein a surface, which faces the backlight module, of the first substrate comprises a plural light-focusing arrays comprising a plural high-refractive areas, each of the high-refractive areas comprises: a first high-refractive area; two second high-refractive areas disposed on both sides of the first high-refractive area symmetrically, wherein the widths of the second high-refractive areas are [the same and] smaller than the width of the first high-refractive area; and a plural low-refractive areas, each of which is disposed between the neighboring high-refractive areas, wherein the refractive index of the low-refractive areas is smaller than that of the first and second high-refractive areas; a second substrate above the first substrate, wherein the second substrate comprises a plural transparent areas right above the light-focusing arrays; a second polarizer on the second substrate; and a liquid crystal layer located between the first substrate and the second substrate.
