Abstract
A method for manufacturing an optical element includes the steps of: providing a first material including a precursor of a first energy curable resin which contains fine particles of a transparent conductive material on a transparent substrate, curing the first material by light irradiation, and performing a heat treatment on the cured first material. In the method described above, the cured first material processed by the heat treatment is again processed by light irradiation.
Claims16
A method for manufacturing an optical element comprising:
- providing a first material including a precursor of a first energy curable resin which contains fine particles of a transparent conductive material on a transparent substrate;
- curing the first material by light irradiation;
- and
- performing a heat treatment on the cured first material,
- wherein the cured first material processed by the heat treatment is again processed by light irradiation (post light irradiation).
