Patent ID: 6847424

Claim:
A reflective liquid-crystal display, comprising: a lighting apparatus, comprising: a light guiding plate including a flat first surface having a plurality of projections, each said projection being formed with a first inclined plane having a first angle between said plane and said flat first surface and with a second inclined plane formed adjacent to said first inclined plane with a second angle between said plane and said flat first surface, said second angle being larger than said first angle and a light source directly coupled to a side surface of said light guiding plate; a reflective liquid-crystal panel disposed on a second surface of said light guiding plate, said second surface opposing said first surface, said reflective liquid-crystal panel opposing said first surface; a polarizer disposed between said reflective liquid-crystal panel and said light guiding plate, said polarizer being directly in contact with said reflective liquid crystal panel; a low-refractive-index layer formed between said polarizer and said light guiding plate, said low-refractive-index layer having a refractive index smaller than a refractive index of said light guiding plate; and another low-refractive-index layer covering said plurality of projections, and having a refractive index smaller than that of the light guiding plate.
