US Patent 7597813 Element substrate and method of manufacturing the same

A method of manufacturing an element substrate including: forming a release layer on a first support substrate; forming a metal layer having a predetermined pattern on the release layer; disposing a second support substrate on the first support substrate so that the metal layer is interposed between the first and second support substrates; pouring a resin material in a fluid state between the first and second support substrates; curing the resin material to form a resin substrate; and removing the metal layer from the first support substrate by decomposing the release layer to transfer the metal layer to the resin substrate.
