Abstract
An in-plane switched liquid crystal device IPS LCD which provides fast switching times is formed by filling an empty IPS LCD panel having an array of display elements with a mixture of nematic liquid crystal material and a mesogenic polymerizable material, such as monomers or polymer precursers and suitable photoinitiators, curing, or cross-linking agents, and then polymerizing the mixture such that a phase-separated network of cross-linked polymer strands is formed. The cross-linked network of polymer strands displays an average orientation whose average orientation substantially conforms with nematic orientation of the nematic liquid crystal material in its “field-off” state.
