Patent ID: 8486608

Claim:
A manufacturing method of a printing substrate for a liquid crystal display comprising: depositing a material layer on an upper surface of a transparent insulating substrate, wherein the material layer is formed of at least one of a-Si, SiNx, and SiOx; depositing a support layer of the same material and the same thickness as the material layer directly on a lower surface of the transparent insulating substrate in order to configure the transparent insulating substrate having the same material of the same thickness on both surfaces so as to reduce a bending of the transparent insulating substrate during a printing process; applying a photo resist directly on the upper side of the material layer, without an intervening metal layer; dry-etching the material layer to form a printing pattern using the photo resist as an etching mask; stripping the photo resist; and forming a transcription layer of a metal or metal oxide on the dry-etched material layer, wherein the printing pattern is more than about 4 μm and less than about 10 μm in width.
