Abstract

The invention discloses a display panel and a manufacturing method thereof. The display panel comprises a substrate; a planarization layer arranged on the substrate; a pixel definition layer arrangedon the planarization layer; a plurality of pixel opening areas, wherein each pixel opening area is arranged on the planarization layer and the pixel definition layer; and a first water blocking film layer arranged in the plurality of pixel opening areas. The planarization layer and the pixel definition layer are respectively provided with pixel opening areas, and the organic planarization layer and the pixel definition layer can be disconnected at intervals through the first water-blocking film layer deposited in the pixel opening areas, so as to form a new water-blocking area, thereby improving the water-blocking effect of a packaging structure. When a laminating adhesive layer is laminated on the substrate in a vacuum manner, the laminating adhesive layer arranged above a test area can also permeate into the pixel opening areas, so that a water blocking effect is achieved, and the water blocking effect of the packaging structure is further enhanced.

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] For the technology of making light-emitting pixels of organic light-emitting diodes (Organic Light-Emitting Diode, OLED for short) with inkjet printing technology, since the film thickness at the edge of the light-emitting area is different from the film thickness of the normal area during printing, a printing test is required. area (Dummy area) to ensure the uniformity of film thickness. However, the printed dummy area is composed of organic materials such as the pixel definition layer and the planarization layer, and the printed dummy area is inside the encapsulation area. Due to the poor water resistance of the organic material, water vapor can easily invade the OLED through the printed dummy area. Since printing the dummy area requires a certain width, in order to ensure the life of the packag...
