Title: DISPLAY SUBSTRATE, MANUFACTURING METHOD THEREFOR AND DISPLAY DEVICE
Abstract:
A display substrate, a manufacturing method therefor and a display device. The manufacturing method for a display substrate comprises: forming a pattern (9) of a first transparent conductive layer; forming a passivation layer and forming a second transparent conductive layer (10) on the passivation layer; forming a pattern of the second transparent conductive layer (10), i.e., a slit-shaped common electrode including a plurality of spaced apart sub-electrodes located in a display region of the display substrate; and removing a portion of the passivation layer not being covered by the sub-electrodes in the display region to form a passivation layer pattern (7). The second transparent conductive layer (10) is polycrystal ITO, and further removing the passivation layer between the sub-electrodes can remove residual polycrystal ITO particles present in the gaps of the slit-shaped electrodes, thereby improving the display effect and improving the transmittance of the display device.
