Patent ID: 6876413

Claim:
A structure of an automatically aligned liquid crystal display comprising: an upper and a lower substrates having respectively a common electrode layer and a pixel electrode layer thereon, one of said electrode layers being transparent and the other being a layer of automatically aligned diffusing reflective device, said automatically aligned diffusing reflective device having at least one convex or concave bump in each pixel region; at least one serial retardation films formed on said upper substrate; a polarizer formed on said serial retardation film; and a uniformly distributed liquid crystal layer formed between said two substrates; wherein said automatically aligned diffusing reflective device further comprises a reflective metal layer and an inner diffusion layer, the average height H of said bump structure is greater than the average height h of said diffusion layer of said reflective device, but less than the liquid crystal cell gap d, liquid crystal molecules in said liquid crystal layer being vertical or near-vertical aligned before applying a driving voltage, and said liquid crystal molecules changing their direction from vertical or near-vertical alignment to slanted or near-horizontal alignment after applying a driving voltage, and the liquid crystal directors near said bumps having pre-tilted angles.
