Method of manufacturing optical film

Abstract

To provide a method of manufacturing an optical film formed on a plastic substrate. There is provided a method of manufacturing an optical film including the steps of laminating a separation layer and an optical filter on a first substrate, separating the optical filter from the first substrate, attaching the optical filter to a second substrate. Since the optical film manufactured according to the invention has flexibility, it can be provided on a portion or a display device having a curved surface. Further, the optical film is not processed at high temperatures, and hence, an optical film having high yield with high reliability can be formed. Furthermore, an optical film having an excellent impact resistance property can be formed.
