Method for manufacturing display substrate, display substrate and display device
A method for manufacturing a display substrate, a display substrate and a display device are disclosed. The method includes: forming a thin-film transistor (TFT) array on a base substrate to form an array substrate; and forming a pixel define layer (PDL) on a non-pixel region of the array substrate by a patterning process. A photochromic material is uniformly distributed in the PDL; the PDL provided with the photochromic material can be converted from light-transmitting to light-shielding under action of light illumination; and the process that the PDL is converted from light-transmitting to light-shielding is irreversible.
