Abstract

The invention discloses a display panel and a manufacturing method thereof. The manufacturing method of the display panel includes the following steps: providing a light-emitting device; coating a polymer solution on the light-emitting device; The light-emitting device is subjected to a first annealing treatment to form a first protective layer; an organic compound solution is coated on the first protective layer, and the organic compound solution is self-assembled on the first protective layer to form a second protective layer. Two protective layers, the second protective layer has a cross-linked three-dimensional network structure. The display panel and its manufacturing method disclosed in the present invention are used to solve the problem that the reliability performance of the display panel is deteriorated due to water vapor entering 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...
