Patent ID: 7863065

Claim:
A method for manufacturing a display substrate, the method comprising: forming an array layer on a substrate, the array layer including a plurality of gate lines, a source metal layer and an activation layer; forming a passivation layer on the array layer; forming a photoresist pattern on the array layer; etching the passivation layer using a mask as the photoresist pattern; non-uniformly surface-treating a surface of the photoresist pattern so that an upper surface of the passivation layer is partially exposed from the surface-treated photoresist pattern overlapping the passivation layer; forming a transparent electrode layer on the substrate including the surface-treated photoresist pattern formed thereon, such that an exposed surface of the surface-treated photoresist pattern is entirely covered by the transparent electrode layer; and forming a pixel electrode, the forming a pixel electrode including removing the photoresist pattern and the transparent electrode layer, the removing the photoresist pattern and the transparent electrode layer including infiltrating a strip solution into the surface-treated photoresist pattern.
