Abstract

The invention relates to the technical field of display, in particular to a display panel, a preparation method thereof and a display device. The technical scheme is used for solving the problems of small contact area and poor lapping stability during lapping of a cathode layer and an auxiliary cathode layer in the prior art. The embodiment of the invention provides a display panel. The display panel comprises a substrate; the at least one second opening is formed in the first conductive pattern layer, the second conductive pattern layer, the third conductive pattern layer and the fourth conductive pattern layer of the substrate, and in the at least one second opening, a first gap is formed between the edge of the orthographic projection of the third conductive pattern layer on the substrate and the edge of the orthographic projection of the fourth conductive pattern layer on the substrate; a second gap is formed between the fourth conductive pattern layer and the bottom edge of the second opening; the surface, away from the substrate, of the part, not covered with the third conductive pattern layer, of the at least one second conductive pattern layer is a first surface, and each first surface is at least provided with a groove in the first gap position.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of self-luminous display technology, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display panel has become a research hotspot due to its good flexibility, high contrast ratio and thinner and thinner characteristics. Contents of the invention [0003] The main purpose of the present invention is to provide a display panel, a manufacturing method thereof, and a display device. It is used to solve the problems of small contact area and poor lap stability when the cathode layer and the auxiliary cathode layer are overlapped in the related art. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] In one aspect, an embodiment of the present invention provides a display panel,...
