Abstract

The invention discloses a pixel defining layer, a display substrate, a manufacturing method thereof, and a display device, and relates to the field of display technology, so that the thickness of the film layer arranged therein is uniform, thereby ensuring the display effect of the display device. The pixel defining layer includes at least one defining unit group located on the base substrate, each defining unit group includes a plurality of defining subunits, each defining subunit includes a defining portion, and each defining unit group A plurality of the delimiting parts are in communication with each other. The display substrate includes the pixel defining layer mentioned in the above technical solution. The pixel defining layer, display substrate, manufacturing method and display device provided by the invention are used in display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel defining layer, a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Inkjet printing technology is a non-contact, pressure-free, and plate-free printing film-forming technology. It has the advantages of simple operation, low cost, and easy realization of large sizes. It is widely used in the field of manufacturing displays. [0003] Specifically, the inkjet printing technology is to dissolve the film-forming material in the solution to make a film-forming solution, and then use the nozzle of the inkjet printer to spray the film-forming solution on the surface of the substrate, so that the film-forming solution is formed on the surface of the substrate and then formed into a film-forming solution. membrane. For example: when making an OLED display substrate, each nozzle of an inkjet printer can be used to simultaneously...
