Surface modification of liquid crystal alignment layer by photochemical reaction
Abstract
The photochemical attachment of functional group of liquid crystal process in the presence of chemical vapor are discussed. A patternable surface chemical property modification scheme by photochemical attachment of a functional group was found. The source of the functional group was supplied as a gas phase material. This scheme can be applied to a photo alignment of liquid crystal display to control its pretilt angle.
