DEFINITION

Classification: 349/134

With particular pretilt angle from the alignment layer:

(under subclass 133) Subject matter wherein the alignment layer causes the chiral smectic liquid crystal molecules near a supporting surface (i.e., substrate) to form a particular angle with the surface.

SEE OR SEARCH THIS CLASS, SUBCLASS:

136, for alignment layers causing a particular pretilt angle for liquid crystals which are not chiral smectic.
