摘要
An anisotropic cross-linked PVA alignment layer for aligning nematic polymeric liquid crystal compensator films, which also provides an out-of-plane retardation. The cross-linked PVA alignment layer, when applied in sufficient thickness functions as both a negative uniaxial C-plate and causes alignment of the nematic liquid crystal molecules. The combination of the retardation provided by the alignment layer and the compensator film deposited on it provides a significant improvement in the contrast and color stability of liquid crystal displays (LCDs) at large viewing angles in which they are used.
