Patent ID: 7283188

Claim:
A liquid crystal display comprising in a layer, a nematic liquid crystal medium that is switchable between at least two different states by application of an electric field, and a compensator comprising only one positive A plate retardation film and only one negative C plate retardation film, wherein the positive A plate retardation film and the negative C plate retardation film are located on different sides of the switchable liquid crystal medium, wherein the positive and the negative retardation films comprise polymerized or crosslinked liquid crystal material, and liquid crystalline molecules in the liquid crystalline medium orient substantially parallel to the plane of the layer when a electric field is applied, the display further comprising a polarizer on each side of the switchable liquid crystal medium, wherein one polarizer is laminated to the positive A plate retardation film such that the optical axis of the A plate and the polarization absorption axis of the polarizer are oriented at 90° to each other, and the other polarizer is laminated to the negative C plate, and wherein the positive A plate and the adjacent polarizer are laminated piece-to-piece and the negative C plate and the adjacent polarizer are laminated roll-to-roll.
