ABSTRACT:
Proposed is a method for manufacturing a color filter having the steps of: forming a stripe- or lattice-shaped light-shield pattern on one major surface of a transparent glass substrate; forming a photosensitive base film on the same major surface of the glass substrate on which the light-shield pattern is formed; exposing the photosensitive base film by light radiated from the other major surface of the glass substrate, using the light-shield pattern as a mask, developing the base film to remove a nonexposed portion of the photosensitive base film immediately above the light-shield pattern and to divide the photosensitive base film along the light-shield pattern; and selectively dyeing divided base film portions to form color layers.
