Abstract:
1. A method for manufacturing a color filter, the color filter comprising a transparent substrate, the method comprising: forming a black matrix on the transparent substrate; and forming at least two colors of resin patterns on the transparent substrate where the black matrix is formed, wherein a process of forming each color of resin patterns comprises: (a) coating a corresponding color of resin layer on the transparent substrate to cover the black matrix and the transparent substrate; and (b) exposing the transparent substrate having the resin layer from two opposite sides of the transparent substrate at the same time, wherein a first group of light is exposed from a side of the transparent substrate adjacent to the black matrix using a photomask, and a second group of light is exposed from another side of the transparent substrate away from the black matrix without using the photomask at the same time when the first group of light is exposed.
