Abstract
A method to fabricate a photo-patterned organic compensator for liquid crystal displays, and the resulting compensator structure, are described. One illustrative fabrication method comprise: (1) depositing a thin film of polymerizable liquid crystal material onto one of a display's substrates; (2) orienting the liquid crystal material's director to a specified direction; (3) polymerizing the deposited thin film through an aperture mask; (4) removing the aperture mask; and (5) curing/annealing the thin film layer to yield a planar structure having substantially birefringent and isotropic regions. Complete pixelated compensators may be created by layering two or more such two-region thin films.
