High brightness liquid crystal display

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.
