摘要： A method for preparing an optical film, which comprises applying and developing an application liquid mixture containing a liquid crystal monomer, a chiral agent and a polymerization initiator on an orientation substrate, subjecting the resultant developed layer to a heat treatment, to orient the monomer to a cholesteric structure, and then subjecting the developed layer to a poltmerization treatment, to polymerize the oriented liquid crystal monomer, thereby forming an optical film exhibiting a selective reflection wave length of 100 to 320 nm. An optical film prepared by the above method is reduced in the coloring due to selective reflection.

摘要： The present invention provides an optical compensation plate having an optical compensation layer in which cracks occurring due to an applied pressure is suppressed. By applying a curable adhesive agent onto at least one surface of the optical compensation layer and curing the adhesive, an anti-cracking layer is formed directly on the surface of the optical compensation layer. The occurrence of cracks in the optical compensation layer can be prevented by this anti-cracking layer. The optical compensation layer preferably is a layer having a cholesteric structure, and the constituent material thereof is preferably a non-liquid crystal polymer formed by polymerizing aligned liquid crystal monomers or an aligned liquid crystal polymer.
