Abstract:
1. A liquid crystal alignment layer in a liquid crystal cell having at least one liquid crystal material, the liquid crystal alignment layer including: a substrate; a first alignment layer continuously disposed on the substrate for inducing a first liquid crystal pretilt angle and a first azimuth angle in the at least one liquid crystal material at the boundary of the at least one liquid crystal material and the liquid crystal alignment layer; and a second alignment layer discontinuously disposed on a surface of the first alignment layer, wherein the second alignment layer independently induces a second liquid crystal pretilt angle and a second azimuth angle in the at least one liquid crystal material at the boundary of the at least one liquid crystal material and the liquid crystal alignment layer; wherein the first and second alignment layers are configured to induce substantially uniform pretilt angles and substantially uniform azimuth angles throughout the at least one liquid crystal material away from the boundary of the at least one liquid crystal material and the liquid crystal alignment layer.
