DEFINITION

Classification: 349/128

With different alignments on opposite substrates:

(under subclass 123) Subject matter wherein the alignment direction and/or pretilt angle of the alignment layer on one side of the liquid crystal material differs from that on the other side of the liquid crystal material.

(1) Note. Different alignments can be formed by using different compositions for the two alignment layers.
