Abstract

The present application discloses a display panel, a manufacturing method thereof, and a display device. The display panel includes an opening area and crack stoppers arranged around the opening area. The transistor device layer and the functional layer in the hole are separated from the hole area; compared with the prior art, the present application effectively prevents cracks in the film layer around the hole area due to cutting during the hole hole process, Furthermore, the encapsulation failure caused by the crack is prevented, the display device in the display panel is protected, and the yield rate of the product is improved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a display panel, a manufacturing method thereof, and a display device having the display panel. Background technique [0002] At present, there is a new type of OLED display panel, which is characterized in that a hole is designed in its surface, and modules such as cameras, infrared sensors, and earpieces can be placed under the hole. Since the position of the hole can be set at will, it can realize The position flexibility of modules such as CUP (under-screen camera), infrared sensor, earpiece, etc. in the panel display area. [0003] However, in the manufacturing process of the existing display panel, since the region of the hole needs to be cut, it is easy to cause cracks in the film layer around the hole, and then the technical problem of packaging failure occurs. Contents of the invention [0004] The embodiment of the present application provides a displa...
