Abstract:
1. A display substrate comprising: a plurality of pixel areas, each pixel area comprising a plurality of sub-pixel areas; a light blocking layer pattern disposed between adjacent sub-pixel areas; and a plurality of color filter patterns corresponding to the sub-pixel areas, wherein each of the color filter patterns has a tapered edge portion and the light blocking layer pattern has a reverse-tapered edge portion, wherein the tapered and reverse-tapered edge portions overlap such that the reverse-tapered edge portion of the light blocking layer pattern is disposed directly on the tapered edge portion of adjacent color filter patterns, wherein the light blocking layer pattern includes an organic material that is non-photosensitive prior to curing, wherein the color filter patterns comprise an organic material that is photosensitive prior to curing, and wherein the light blocking layer pattern has a concave upper surface, and a height at an edge of the light blocking layer pattern is greater than a height at a center of the light blocking layer pattern.
