Abstract
A method of manufacturing an optical film includes steps of providing a substrate first and performing an alignment treatment on the surface of the substrate or forming an alignment layer on the substrate. A first liquid crystal layer is then coated on the aligned surface of the substrate or on the surface of the alignment layer, and thereafter, a first curing step is performed. After a second alignment layer is coated on the surface of the first liquid crystal layer, a second curing step is performed so as to form a multi-layer including the first and second liquid crystal layers.
