Embodiment Construction

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0050] An embodiment of the present invention provides a pixel defining layer, the pixel defining layer includes a pixel partition wall pattern, and the upper surface of the pixel partition wall has a depression. Such as image 3 As shown, the upper surface of the pixel separation wall 15 is inwardly recessed at the middle part to form a groove.

[0051] It should be noted that in all the embodiments of the present invention, the definitions of "layer" and "pattern" and the relationship between them need to be clarified. Wherein, "layer" refers to a layer of thin film made of a certain material on a substrate by deposition or other processes, which includes a "patte...

Abstract

The invention provides a pixel defining layer, a manufacturing method thereof, a display substrate and a display device, which belong to the technical field of display and solve the problem that the current inkjet printing ink slightly overflows to adjacent pixel areas to cause poor display. The pixel defining layer comprises pixel division wall patterns, and pits are formed in the upper surfaces of pixel division walls.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel defining layer and a manufacturing method thereof, a display substrate and a display device. Background technique [0002] Inkjet printing technology is one of the main technologies used in modern office printing. In recent years, researchers have begun to try to apply inkjet printing technology to the preparation of planar functional materials, such as the preparation of polymer conductive films, the preparation of color organic light-emitting diodes, the preparation of Thin film semiconductor devices, etc. [0003] Existing (Organic Light Emitting Diode, Organic Light Emitting Diode) display devices, such as figure 1 As shown, the OLED display substrate includes a base substrate 11 , an anode electrode layer 12 disposed on the base substrate 11 , a light emitting function layer 13 , and a cathode electrode layer 14 . The display device includes a plurality of pixel r...
