Abstract

The invention discloses a display substrate, a manufacturing method thereof and a display device. The display substrate comprises a substrate, a pixel definition layer and an organic light emitting functional layer, and is characterized in that the pixel definition layer defines a plurality of spaced pixel regions and enables the pixel regions to form grooves, and the pixel definition layer comprises a first pixel definition layer and a second pixel definition layer; the first pixel definition layer is arranged at one side of the substrate; the second pixel definition layer is arranged at the side, which is back to the substrate, of the first pixel definition layer; the second pixel definition layer is located between a flat plane / curved plane defined by the side wall of the first pixel definition layer and a flat plane defined by the substrate; and the organic light emitting functional layer covers the surface of the pixel definition layer and fills the grooves formed by the pixel definition layer and the substrate. According to the above scheme, the display substrate can solve or relieve a problem of light leakage of the existing OLED display.

Description

technical field [0001] The invention relates to the field of display equipment, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] As more and more organic light-emitting diodes (OLEDs) are used in display devices, the display technology of the organic light-emitting diodes continues to develop towards a high-resolution trend while ensuring the brightness of the display devices. [0003] With the improvement of the resolution of the organic light emitting diode display, the pitch between the pixels of the display is getting smaller and smaller, which makes the display device prone to light leakage. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a display substrate, which can increase the height of the pixel definition layer of the display substrate, thereby solving the light leakage problem without affecting the light-emitting viewing angle ...
