Abstract:
1. An exposure apparatus for exposing a photo-resist layer on a transparent substrate, wherein a transparent electrode layer is positioned between the photo-resist layer and the transparent substrate, characterized in that: the exposure apparatus comprises: a mask disposed at one side of the transparent substrate, wherein the photo-resist layer is positioned at an opposite side of the transparent substrate for patterning the transparent substrate; an exposure light source configured to provide light rays to the photo-resist layer, wherein the light rays provided by the exposure light source pass the mask and the transparent substrate to reach the photo-resist layer; a reflective plate disposed at the opposite side of the transparent substrate and faces to the photo-resist layer for reflecting the light rays passing through the transparent substrate and the photo-resist layer back to the photo-resist layer; and a projection reduction lens system disposed between the mask and the transparent substrate for projecting the light rays passing through the mask to a bottom surface of the photo-resist layer, wherein the mask is positioned to the photo-resist layer on the transparent substrate by using an aligner.
