Abstract

The invention discloses a display panel and a manufacturing method thereof. The manufacturing method of the display panel comprises the following steps: providing a light-emitting device; coating thelight-emitting device with a polymer solution, and performing first annealing treatment on the light-emitting device coated with the polymer solution to form a first protective layer; and coating thefirst protective layer with an organic compound solution, so that the organic compound solution is self-assembled on the first protective layer to form a second protective layer, and the second protective layer has a cross-linked three-dimensional network structure. The display panel and the manufacturing method thereof are used for solving the problem that the reliability of the display panel becomes poor due to the fact that water vapor enters the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] In an existing organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel, an encapsulation cover plate is generally arranged above the OLED device to package the OLED device. The existing display panel includes a substrate, a display device, an encapsulation substrate for encapsulating the display device, a sealant, and a hydrophobic retaining wall located at the outermost layer of the encapsulation area. However, the existing packaging structure and the display device have poor contact, and water vapor easily enters the display panel, resulting in low performance and poor reliability of the display panel. [0003] Therefore, it is necessary to propose a new technical solution to solve the above technical problems. Contents of the invention [0004] Embodiments of the pres...
