Patent ID: 7518680

Claim:
An active matrix type liquid crystal display, comprising: an in-plane switching type liquid crystal display panel having an active device substrate, an opposing substrate and a liquid crystal layer held sandwiched between said active device substrate and said opposing substrate; a first polarizer laid out on one side of said liquid crystal display panel; a second polarizer laid out on the opposite side of said liquid crystal display panel; a first optical compensator, placed between said first polarizer and said second polarizer, for compensating for retardation of said liquid crystal layer; and a second optical compensator, placed between said first polarizer and said second polarizer, for compensating for retardation of said first and second polarizers, wherein said first polarizer is laid out on an opposing substrate side of said liquid crystal display panel, said first and second optical compensators are laid out in order between said liquid crystal display panel and said first polarizer from a liquid crystal display panel side, and a direction of each of refractive indexes nx of said first and second optical compensators is set parallel to or perpendicular to an alignment direction of said liquid crystal layer.
