However, in the prior art, the special-shaped display panel includes a display area, a black matrix area, and a transition area. In order to avoid light leakage, the transition area also needs to be filled with a black matrix material. Based on this structure, since the conventional pixel shape is rectangular, it is necessary to meet the boundary of these special-shaped cutting, so that the periphery of the special-shaped panel forms an arc, hypotenuse, etc., and the pixels in the display area can only be arranged in a zigzag according to the shape of the boundary. Shape, forming a jagged edge, and these jagged pixels arranged on the edge of the irregular shape can only be approximately arc or bevel, which will result in jagged pixels at the edge of the display area with display brightness and completely dark A strong brightness contrast is formed between the transition areas, so that the display panel can see the unsmooth boundary line on the macroscopic view, and even see the jaggedness directly, which reduces the visual effect of the edge of the display panel and seriously affects the user experience.

In summary, the existing special-shaped display panel has the problem that the edge of the display area is not smooth. Therefore, it is necessary to provide a pixel structure, a display panel, and a display device to improve this defect.
