Abstract

The invention provides a display substrate and a preparation method thereof, a display panel and a display device. The preparation method comprises the following steps: providing a substrate; formingan anode layer on the substrate and a hole injection layer located on the anode layer, wherein the anode layer comprises a plurality of anode blocks arranged at intervals, the hole injection layer comprises hole injection parts located on each anode block, and the adjacent hole injection parts are arranged at intervals; forming a pixel limiting layer located on the hole injection layer, wherein the pixel limiting layer is provided with a plurality of pixel openings in one-to-one correspondence with the plurality of hole injection parts, and the pixel openings expose the corresponding hole injection parts; forming an organic light-emitting material layer, wherein at least part of the organic light-emitting material layer is located in the pixel opening; and forming a cathode layer, whereinthe cathode layer covers one side, deviating from the substrate, of the organic light-emitting material.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display substrate and a preparation method thereof, a display panel, and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) has the advantages of wide viewing angle, fast response, high contrast ratio, etc., and has been widely used in display devices. [0003] The existing OLED display device has the problem of crosstalk between adjacent sub-pixels of different colors when displaying. The color problem, especially in the low gray scale, affects the user experience. Contents of the invention [0004] According to the first aspect of the embodiments of the present application, a method for preparing a display substrate is provided. Described preparation method comprises: [0005] provide the substrate; [0006] An anode layer and a hole injection layer located on the anode layer are formed on the sub...
