SAPONIFICATION METHOD FOR OPTICAL COMPENSATION SHEETS

摘要

PURPOSE: A saponification method of an optical compensating sheet is provided to prevent the deterioration of a viewing angle compensation effect without additional equipment and process in order to solve a problem about detecting test liquid. CONSTITUTION: An optical compensation sheet is formed on the transparency based parts film in which the number contact angle of the transparent film is formed. The optical compensation sheet includes an orientated layer for constituting the optically anisotropic layer on the transparency based parts film. The contact angle of the optical compensation sheet is between 29 and 30 degrees.
