Problems solved by technology

However, if the material of the pixel defining layer is reduced to 1um, the amount of ink droplets that can be contained in the sub-pixel area will be reduced. Therefore, reducing the material thickness of the pixel defining layer to suppress the climbing of ink droplets and maintain the loading capacity of ink droplets cannot be achieved at the same time. Satisfy

Abstract

The invention discloses a pixel defining structure and a manufacturing method thereof, a display substrate and a display device. The pixel defining structure includes at least two layers of ladder structures arranged in a ladder shape. The pixel defining structure limits ink droplets to flow into sub-pixel regions , On the one hand, the climbing height of the ink droplet can be suppressed from being too high, and on the other hand, the loading capacity of the ink droplet can be maintained.

Description

technical field [0001] The invention relates to the field of display devices, in particular to a pixel defining structure, a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Compared with Liquid Crystal Display (LCD), Organic Light-Emitting Diode (OLED) has the advantages of self-illumination, fast response, wide viewing angle, high brightness, bright color, light and thin, etc. next generation display technology. [0003] OLED film-forming methods mainly include evaporation process or solution process. The evaporation process is relatively mature in small-scale applications, and this technology has been applied in mass production. The solution process OLED film-forming methods mainly include inkjet printing, nozzle coating, spin coating, screen printing, etc. Among them, inkjet printing technology is considered to be a large-scale OLED technology due to its high material utilization rate and large-scale realization.
