Abstract
A display substrate and a manufacturing method thereof are disclosed. The display substrate is divided to have a non-pixel region and a color pixel region. The manufacturing method includes: forming a thin film transistor (TFT) on a base substrate in the non-pixel region; forming a passivation layer on the TFT; forming a color filter on the passivation layer in the color Pixel region; forming a planarization layer on the passivation layer and the color filter; thinning a thickness of a portion of the planarization layer located in the color pixel region; and forming a display electrode on the planarization layer and connecting the display electrode to a drain electrode of the TFT through a via hole.
