| 1. A method for manufacturing a color filter, comprising the steps of:
defining a plurality of grooves in a surface of a transparent substrate;
applying a black organic material into the plurality of grooves to form an organic black matrix;
forming a positive photoresist layer 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 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.
