Abstract

A method of preparing a composite optical retarder is provided. A first and a second liquid crystal coating materials are respectively disposed on opposite surfaces of a photoalignment film to respectively form a first and a second optical retarders. The composite optical retarder having the photoalignment film sandwiched by the first and the second optical retarders is thus obtained.
