Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device. The display panel includes: an array layer; a light-emitting device layer located on the array layer; a package structure located on the side of the light-emitting device layer away from the array layer, and the package structure includes a metal oxide layer; an adhesive layer located on the side of the package structure away from the light-emitting device layer ; Wherein, the orthographic projection of the packaging structure on the array layer is located within the orthographic projection of the adhesive layer on the array layer, and the orthographic projection of the adhesive layer on the array layer is larger than the orthographic projection of the packaging structure on the array layer. The bonded edge of the adhesive layer is not in contact with the metal oxide layer produced by the atomic layer deposition process, which avoids warping or even peeling off at this position due to poor bonding performance, and ensures the performance reliability of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the continuous development of science and technology, more and more display devices are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable tool for people today. . [0003] Display panels in the prior art are mainly divided into two types: liquid crystal display panels and organic light emitting display panels. The main difference between a liquid crystal display panel and an organic light-emitting display panel is that a backlight is required in a liquid crystal display panel, and the backlight emits light to realize display by controlling the deflection of liquid crystal molecules in the display panel, while organic light-emitting materials in an organic light-emitti...
