Abstract
A method for manufacturing an optical device and an optical device is provided. The manufacturing method is 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 method of the present application can provide an alignment film having improved orientation by improving the dotting unevenness.
