Abstract:
1. A method of manufacturing a display substrate, comprising: forming a gate pattern on a base substrate using a first photo-resist pattern; sequentially forming a gate insulation layer, a channel layer, and a source metal layer on the base substrate having the gate pattern formed thereon; patterning the source metal layer using a second photo-resist pattern to form a source pattern; forming a protective insulation layer on the base substrate having the source pattern formed thereon; patterning the protective insulation layer and the gate insulation layer using a third photo-resist pattern to expose a portion of the base substrate; forming a color filter pattern on the exposed portion; and forming a pixel electrode on the base substrate having the color filter formed thereon, wherein patterning the protective insulation layer and the gate insulation layer using a third photo-resist pattern to expose a portion of the base substrate comprises:
