Abstract

The invention discloses a method for manufacturing a display substrate, which belongs to the technical field of display. The method includes: providing a base substrate; forming a thin film transistor TFT on the base substrate; forming a photoresist pattern on the base substrate on which the TFT is formed, and the photoresist pattern includes a A hollow area of ​​the spacer pattern; forming a spacer material in the hollow area; stripping the photoresist pattern, so that the spacer material in the hollow area forms the spacer pattern. The invention solves the problem in the related art that the brightness of the pixels on the display device may be uneven when the display substrate is manufactured, which affects the stability of the image display of the display device. The invention is used in the manufacture of display substrates.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a display substrate. Background technique [0002] An organic light-emitting diode (English: Organic Light-Emitting Diode; abbreviation: OLED) display device is a display device with an autonomous light emitting function. The OLED display device includes a plurality of pixels arranged in a matrix, and the OLED display device can be divided into an active matrix organic light emitting diode (English: ActiveMatrix / Organic Light Emitting Diode; abbreviation: AMOLED) display device and an OLED display device according to the driving method of its pixels. Source matrix organic light-emitting diode (English: Passive matrix Organic Light-Emitting Diode; abbreviation: PMOLED) display device, among which, AMOLED display device is characterized by its thin thickness, light weight, active light emission, fast response speed, wide viewing angle, rich colors and hi...
