Abstract

The invention discloses a display panel and a display device. The two adjacent pixel units in the display panel are respectively the first pixel unit and the second pixel unit, the edge of the first pixel unit close to the source via hole is the first edge, and the edge of the second pixel unit close to the source via hole is the second edge, along the extension direction of the scanning line, the minimum distance between the edge of the source via hole and the first edge is A, the minimum distance between the edge of the source via hole and the second edge is B, and A is smaller than B; The first color filter unit corresponds to the first pixel unit. Along the extending direction of the scanning line, a raised structure is formed on at least one side of the black matrix close to the first color filter unit. The raised structure is arranged corresponding to the source via hole. The technical solution provided by the embodiment of the present invention enables the black matrix to better cover the source via hole, thereby avoiding dark state light leakage at the location of the source via hole and improving the display effect of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display panel and a display device. Background technique [0002] With the continuous development of display technology, display devices are used in various fields of social life and are favored by users. [0003] The display panel is the core component of the display device. With the continuous improvement of the manufacturing process, the line width of each structure in the display panel is getting smaller and smaller, and the pixel density of the display panel is increasing accordingly. The source via hole and drain electrode in the pixel unit The distance between the vias becomes smaller, and the capacitive coupling between the two increases. In order to solve the above problems, the method adopted in the prior art is to move the position of the source via hole so that the source via hole is far away from the drain via hole. However, in this method, the s...
