ABSTRACT:
A method for making an optical device comprises steps of: 1) Providing a substrate, a polymerizable liquid crystal material having a plurality of liquid crystal molecules, and a mold having rows of trenches; 2) Imprinting the polymerizable liquid crystal material on said substrate by the mold; 3) Proceeding a cross-linking process to cure the liquid crystal material so as to have long axes of the liquid crystal molecules be aligned along the rows of trenches. The optical device made from the present method conforms to an A-plate type retardation plate. Moreover, the optical device is capable of aligning liquid crystal molecules adjacent to it.
