DEFINITION

Classification: 349/130

For perpendicular alignment:

(under subclass 123) Subject matter wherein the alignment layer causes the liquid crystal molecules to be oriented homeotropically or substantially perpendicular to a supporting surface (i.e., substrate).

(1) Note. This type of alignment is typically found in conjunction with dynamic scattering or variable birefringence type liquid crystal devices.
