AI Technical Summary
Technical Problem
Inadequate encapsulation of OLED display panels leads to poor encapsulation results and affects display performance.
Method used
The design employs an isolation structure and an encapsulation layer. The isolation structure comprises inorganic materials, and the encapsulation layer is composed of inorganic and organic materials. By setting a first encapsulation layer on the side of the isolation structure away from the substrate to cover the isolation structure, the continuity and sealing performance of the encapsulation layer are enhanced.
Benefits of technology
It improves the encapsulation effect of the display panel, enhances the sealing performance, prevents water and oxygen intrusion, and strengthens the encapsulation effect of the display panel.

Abstract
Embodiments of the present application provide a display panel and a display device, the display panel comprising: a substrate; a pixel definition layer disposed on the substrate, the pixel definition layer comprising a pixel limiting portion and a pixel opening formed by the pixel limiting portion, and a light-emitting layer disposed in the pixel opening; an isolation structure disposed on a side of the pixel limiting portion away from the substrate; a first electrode located on a side of the light-emitting layer away from the substrate; and an encapsulation layer located on a side of the first electrode and the isolation structure away from the substrate, the encapsulation layer comprising a first encapsulation layer in contact with the first electrode, and the first encapsulation layer covering the isolation structure. The side of the pixel definition layer away from the substrate is provided with the isolation structure and the first electrode, and the first encapsulation layer in contact with the first electrode on the encapsulation layer covers the isolation structure, that is, the first encapsulation layer covers the first electrode and the isolation structure at the same time, which can improve the continuity of the first encapsulation layer, thereby improving the sealing performance of the encapsulation layer and the encapsulation effect of the display panel.
