摘要： The present application relates to a method for manufacturing an optical device and an optical device. The present application provides a manufacturing method capable of minimizing or eliminating dotting unevenness that may occur when an optical device is manufactured by a dotting process. In particular, even when a large cell gap is present or a polymer substrate is applied as a substrate so that high-temperature heat treatment is impossible, such a method of the present application can provide an alignment film having improved orientation by improving the dotting unevenness.
