Method of manufacturing optical compensation sheet comprising coating liquid crystal layer wider than oriented layer
View Patent ↗A method of manufacturing an optical compensation sheet, comprising the steps of: an oriented layer coating step in which an oriented layer is coated on the surface of a long substrate while the substrate is running; and a liquid crystal layer coating step in which a liquid crystal layer is coated on the oriented layer, wherein the liquid crystal layer is coated wider than the oriented layer, thereby covering the oriented layer with the liquid crystal layer.
1. A method of manufacturing an optical compensation sheet, comprising the steps of:
an oriented layer coating step in which an oriented layer is coated on the surface of a long substrate while the substrate is running; and
a liquid crystal layer coating step in which a liquid crystal layer is coated on the oriented layer,
wherein the liquid crystal layer is coated wider than the oriented layer, thereby covering the oriented layer with the liquid crystal layer.
2. The method of manufacturing an optical compensation sheet according to claim 1 , further comprising: before the oriented layer coating step, a saponification step in which the surface of the substrate is saponified wider than the oriented layer is coated,
wherein the oriented layer is coated within the area saponified in the saponification step.
