Patent ID: 8722440

Claim:
A method of manufacturing a display substrate, comprising: forming a gate electrode on a substrate, forming a gate insulating layer on the gate electrode, and forming a semiconductor layer on the gate insulating layer; forming a color filter layer on the substrate and on the semiconductor layer, so as to expose a portion of the semiconductor layer; forming a source electrode and a drain electrode spaced apart from the source electrode, each of the source electrode and the drain electrode disposed on the semiconductor layer and the color filter layer; forming a protective layer on the semiconductor layer, the color filter layer, the source electrode, and the drain electrode; and forming a pixel electrode on the protective layer, the pixel electrode being connected to the drain electrode, wherein the protective layer is disposed directly on the exposed portion of the semiconductor layer, and wherein the color filter layer directly contacts a side portion of the semiconductor layer, and the color filter layer extends to an edge of the semiconductor layer.
