Abstract
A method of making nematic liquid crystal devices where low energy zenith anchoring of the liquid crystal is obtained over confinement plates. A polymer or copolymer is deposited based on PVC onto a substrate. The polymer deposit is stabilized. An azimuth orientation is defined for the deposit to induce controlled azimuth anchoring of the liquid crystal.
