Abstract

The present invention relates to a display panel, a manufacturing method thereof, and a display device. The display panel includes a substrate, a light-emitting device arranged on the substrate, and an encapsulation layer covering the light-emitting device. The encapsulation layer includes a first inorganic encapsulation film layer, an alignment encapsulation film layer and a second inorganic encapsulation film layer that are stacked in sequence, and the alignment encapsulation film layer The side away from the substrate has a plurality of nano-scale grooves arranged in parallel along a predetermined direction. In the display panel, the manufacturing method and the display device provided by the present invention, since the side of the alignment packaging film layer away from the substrate has a plurality of nano-scale grooves arranged in parallel along a preset direction, when cracks occur in the inorganic packaging film layer, the alignment packaging film layer The groove on the film layer can extend the water and oxygen intrusion path, and the nano-scale groove has a smaller size, and it is difficult for water and oxygen to invade into the groove, which increases the difficulty of water and oxygen to corrode the light-emitting device, so it can improve the efficiency of water and oxygen. The water and oxygen barrier capability of the display panel prolongs the life of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Thin-film encapsulation is an encapsulation method widely used in the production of OLED (Organic Light-Emitting Diode, organic light-emitting diode) display panels. Purpose. [0003] However, the thin-film encapsulation of the existing display panel still has the problem of poor water and oxygen barrier. SUMMARY OF THE INVENTION [0004] Based on this, it is necessary to provide a display panel, a method for manufacturing the same, and a display device that improve the above-mentioned problems in view of the problem of poor barrier water and oxygen in the thin film packaging of the existing display panel. [0005] According to one aspect of the present invention, there is provided a display panel, comprising: [0006] substrate; [0007] a light-emitting devic...
