Organic luminous display panel, manufacturing method thereof and display device

Abstract

The embodiment of the invention provides an organic luminous display panel, a manufacturing method of the organic luminous display panel, and a display device, and relates to the technical field of electroluminescent display. The organic luminous display panel can solve the problem that the overall performance of a device is reduced due to the fact that liquid organic luminous materials at the edge of a pixel defining layer in an organic luminous display panel are prone to flowing outwards. The organic luminous display panel comprises a pixel defining layer located in a display region of the organic luminous display panel, the pixel defining layer is provided with a plurality of openings, and the openings are used for arranging organic luminous function layers; the organic luminous display panel further comprises a blocking layer surrounding the pixel defining layer; the pixel defining layer and the organic luminous function layers are identical in hydrophilia and hydrophobicity, and the blocking layer and the organic luminous function layers are opposite in hydrophilia and hydrophobicity. The manufacturing method of the organic luminous display panel is used for manufacturing the organic luminous display panel.

Description

technical field [0001] The invention relates to the technical field of electroluminescence display, in particular to an organic light-emitting display panel, a preparation method thereof, and a display device. Background technique [0002] Compared with Liquid Crystal Display (LCD), Organic Light-Emitting Device (OLED) has the advantages of self-illumination, fast response, wide viewing angle, high brightness, bright color, and thinness. It is considered to be the next generation of mainstream display technology. [0003] like figure 1 As shown, the main structure of the OLED display device is an OLED device, including a substrate 10 , an anode electrode layer 11 , an organic light-emitting functional layer 30 , and a cathode electrode layer 12 . Among them, the organic light-emitting functional layer 30 is the core structure of the OLED device, mainly composed of a hole injection layer 31, a hole transport layer 32, a light-emitting layer 33, an electron transport layer 3...

AI Technical Summary

Problems solved by technology

[0007] In view of this, in order to solve the problems in the prior art, the embodiments of the present invention provide an organic light-emitting display panel, its manufacturing method, and a display device, which can solve the problem of the pixel-defining layer when the organic light-emitting material is coated on the entire surface by the solution method. At the edge, the liquid organic light-emitting material is easy to flow out freely, causing the performance degradation of the OLED display panel and the increase of the non-display area area.
