Abstract

The invention discloses a display substrate manufacturing method and belongs to the technical field of display. The method comprises the following steps: providing a substrate; forming a thin film transistor (TFT) on the substrate; forming a photoresist pattern on the substrate having the TFT formed thereon, wherein the photoresist pattern comprises a hollow area for forming a spacer pattern; forming spacer material in the hollow area; and stripping the photoresist pattern to enable the spacer material in the hollow area to form the spacer pattern. The display substrate manufacturing method solves the problem that image display stability of a display device is influenced due to possible pixel brightness nonuniformity of the display device when the display substrate is prepared in the prior art. The method is used for manufacture of the display substrate.

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...
