Abstract
A method for forming an assay of microcompensators having a pattern of sub-pixel-sized regions of a light sensitive resin, which has been dispersed a colored pigment, aligned with the microcompensators for phase compensation.
Claims5
A method for forming an array of microcompensators, comprising:
- (a) providing a substrate;
- (b) depositing a birefringent layer on said substrate;
- (c) heating said birefringent layer and said substrate;
- (d) depositing a layer of a light sensitive resin within which has been dispersed a colored pigment;
- (e) exposing and then developing said light sensitive resin to form a pattern of sub-pixel-sized regions and then, using an etchant which does not attack the developed resin, removing all birefringent material not covered by the resin;
- (f) heating said birefringent layer, said developed resin, and said substrate;
- and
- (g) optionally repeating steps (b) through (f) at least one more time.
