TLDR
In this article, a pixel defining layer is used for manufacturing the display substrate of an organic light-emitting diode, which is used to enable the climbing quantities of different kinds of solution on the corresponding pixel defining layers to be the same, thereby effectively improving the film forming uniformity of solution in the pixel regions.Abstract:
The invention discloses a pixel defining layer, a manufacturing method, a display substrate, and a display device, and belongs to the field of display. The pixel defining layer comprises a lyophilic material layer disposed on a substrate, and a lyophobic material layer which is disposed at one side, far from the substrate, of the lyophilic material layer. The pixel defining layer limits a plurality of pixel regions arranged in an array on the substrate, wherein each pixel region comprises at least two subpixel regions, and the thicknesses of lyophilic material layers of different subpixel regions in the same pixel region are set to be different. The pixel defining layer can enable the climbing quantities of different kinds of solution on the corresponding pixel defining layers to be the same, thereby effectively improving the film forming uniformity of solution in the pixel regions. The pixel defining layer is used for manufacturing the display substrate of an organic light-emitting diode.read more
