Abstract
A process for producing an optical compensation film comprises a liquid crystal layer application step () of applying a liquid crystal layer coating solution containing a liquid crystal compound to an alignment layer on a surface of a transparent substrate () that is continuously transported; a liquid crystal layer drying step () of drying the liquid crystal layer; a cooling and curing step of curing the liquid crystal layer while cooling the liquid crystal layer to a temperature lower than a drying temperature used in the drying step; and a heating and curing step of curing the alignment layer while heating the alignment layer to a temperature higher than a cooling temperature used in the cooling and curing step. The process enables the durability and damage resistance as well as the optical characteristics of the optical compensation film to be independently controlled.
