Abstract

The embodiment of the invention discloses a display panel, a display device and a manufacturing method of the display panel. The display panel comprises an array substrate, an anode layer, a pixel definition layer, a fence layer and a cathode layer which are arranged in sequence, the array substrate comprises a substrate and a lap joint layer which are arranged in sequence, the lap joint layer comprises a lap joint part, the anode layer is provided with a first opening and exposes the lap joint part, and the pixel definition layer is provided with a second opening corresponding to the first opening. The fence layer comprises a fence part, the fence part extends along the edge of the second opening, and the cathode layer penetrates through the first opening and the second opening to be electrically connected with the lap joint part. According to the display panel, the fence part is arranged on the pixel definition layer and extends along the edge of the second opening, so that in the process of manufacturing the display panel, the fence part can play a supporting and protecting role, the lap joint part can be conveniently exposed, the cathode layer and the lap joint part can be effectively and electrically connected, the risk that the area outside the fence part is etched can be reduced, and the display quality is improved. And the lap joint effect of the cathode layer and the lap joint part is improved.

Description

technical field [0001] The present application relates to the field of display, and in particular, to a display panel, a display device and a manufacturing method of the display panel. Background technique [0002] With the rapid development of display panels, the demand for large-size display panels is also increasing. However, when the large-size display panels work, there are internal resistance voltage drops at different positions of the display area of ​​the display panel, resulting in uneven display of the display panel as a whole. For this reason, it is often used in the array substrate of the display panel to make an overlap layer as an auxiliary electrode and form an undercut structure at a corresponding position on the overlap layer, and then connect the cathode layer and the overlap layer to the area with a large voltage drop. Additional auxiliary is applied, so that the picture display is uniform and stable when the entire display panel is working. However, in t...
