Title: DISPLAY SUBSTRATE, LIQUID CRYSTAL PANEL, DISPLAY DEVICE, AND MANUFACTURING METHOD FOR DISPLAY SUBSTRATE
Abstract:
A display substrate, a liquid crystal panel, a display device, and a manufacturing method for the display substrate. The display substrate comprises a plurality of pixel regions (10), and a groove (11) formed between two adjacent pixel regions (10). The display substrate further comprises a spacer layer (12), and the spacer layer (12) comprises a filling portion (121) filled into the groove (11) and a support portion (122) protruding from the filling portion (121). The groove (11) formed between adjacent pixel regions (10) is filled with the filling portion (121), so that the surface flatness of the display substrate is increased, the phenomenon of poor image persistence of the display device is effectively improved, and the display quality of the display device is improved. The support portion (122) is used for supporting an upper substrate and a lower substrate. The support portion (122) and the filling portion (121) are integrally formed, and the connecting strength is high. In the rubbing alignment process, the columnar support portion (122) is not prone to disengagement and will not pollute alignment liquid, and therefore the manufacturing quality of the display device is improved.
