Abstract
A method for manufacturing a color filter includes the steps of: forming an organic black photoresist layer (304) on a transparent substrate (300); exposing the organic black photoresist layer using a photo-mask; developing the organic black photoresist layer to form an organic black matrix (3041) on the transparent substrate; forming a positive photoresist layer (306) on the transparent substrate thereby covering the organic black matrix with the positive photoresist layer; irradiating a surface of the transparent substrate facing away from the positive photoresist layer so as to expose the positive photoresist layer; developing the positive photoresist layer to form a plurality of banks (3061) on the organic black matrix; injecting ink into spaces defined by the banks and the organic black matrix using an ink-jet device; and solidifying the ink.
