Problems solved by technology

However, the inorganic layer is relatively thin, and the stress of the inorganic layer is large, so cracks are prone to appear around the thin film packaging structure, and water and oxygen can easily invade the OLED device through these cracks, causing damage to the OLED device, thereby affecting the service life of the display panel.

Abstract

The invention discloses a display panel, a production method of the display panel and a display device. The display panel comprises a display area, wherein the display area comprises a pixel limitinglayer, organic light emitting units and a packaging structure, wherein the pixel limiting layer comprises multiple pixel definition areas distributed in array and pixel limiting areas surrounding thepixel definition areas; pixel definition openings are formed in the pixel definition areas and packaging definition openings are formed in the pixel limiting areas; organic light-limiting units are formed in the pixel definition openings; the packaging structure comprises first packaging parts filling the packaging definition openings and a second packaging part covering the pixel definition areasand the pixel limiting areas and connected with the first packaging part to package the organic light-emitting units. The second packaging part is used for packaging the organic light-emitting units,and the first packaging parts are used for enhancing the packaging strength, so that the problem that cracks or stripping is easily caused under the action of internal force or external force with aconventional packaging structure is solved, the packaging reliability is improved, and the service life of the display panel is prolonged.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] At present, the display panel adopts a thin film packaging structure to encapsulate an OLED (Organic Light-Emitting Diode, OLED) device to achieve packaging. The inorganic layer of the thin-film encapsulation structure has high compactness and can be used to block the intrusion of water and oxygen. However, the inorganic layer is thinner and the stress of the inorganic layer is large. Therefore, cracks are prone to appear around the thin film packaging structure. Water and oxygen can easily penetrate into the OLED device from these cracks, causing damage to the OLED device, thereby affecting the service life of the display panel. Summary of the invention [0003] Based on this, it is necessary to provide a display panel, a manufacturing method thereof, and a display device tha...
