Abstract: In a method for manufacturing a display substrate, a thin film transistor is formed on a base substrate. The thin film transistor includes a gate electrode, an active pattern, a source electrode and a drain electrode. A first passivation layer is formed to cover the thin film transistor. A second passivation layer is formed on the first passivation layer. A photoresist pattern is formed to partially expose the second passivation layer. The first passivation layer and the second passivation layer are partially removed to form a contact hole exposing the drain electrode. A pixel electrode layer is formed on the second passivation layer, the drain electrode and the photoresist pattern. A portion of the pixel electrode layer and the second photoresist pattern are removed to form a pixel electrode. The portion of the pixel electrode layer is disposed on a top surface and a sidewall of the photoresist pattern.
