Abstract
A multi-domain in-plane-switching liquid crystal display with small color shift, wide viewing angle and fast response. The structure of the multi-domain in-plane switching liquid crystal displays comprises plural chevron-shaped common electrodes and chevron-shaped pixel electrodes, arranged alternatingly to form a multi-domain liquid crystal distributions. In an embodiment the structure includes a polarizer and an analyzer and the liquid crystal material is homogenously aligned. In another embodiment the structure includes alignment films for vertically aligning the liquid crystal material and crossed linear polarizers, circular polarizers or a combination of linear polarizers and compensation film. In another embodiment, the multi-domain in-plane switching liquid crystal display provides at least two different uniformly aligned liquid crystal domains, for a double multi-domain-In-plane switching LC display.
