Abstract

The invention discloses a display panel and a display device. Two adjacent pixel units in the display panel are a first pixel unit and a second pixel unit respectively. The edge, which is near a source via hole, of the first pixel unit is a first edge. The edge, which is near the source via hole, of the second pixel unit is a second edge. The minimum distance A between the edge of the source via hole and the first edge along the extending direction of a scan line is A. The minimum distance between the edge of the source via hole and the second edge is B, and A is less than B. A first color filter unit corresponds to the first pixel unit. A protruding structure is formed along at least a side, which is near the first color filter unit, of a black matrix in the extending direction of the scan line. The protruding structure is corresponding to the source via hole. According to the technical scheme provided by the embodiment of the invention, the black matrix can cover the source via hole;the phenomenon of dark-state light leakage at the position where the source via hole is located is avoided; and the display effect of the display panel is improved.

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...
