Abstract

The invention discloses a display panel and a display device, and the display panel comprises a substrate, a first electrode layer, a first insulating layer, a second electrode layer, a second insulating layer, a third electrode layer, a first gate line, a second gate line, a line-changing connection block, a common electrode line, and a first low-potential gasket, wherein the first electrode layer, the first insulating layer, the second electrode layer, the second insulating layer and the third electrode layer are located on the substrate in order, the first electrode layer comprises a firstgate line, the second electrode layer comprises a second gate line, the third electrode layer comprises a line changing connecting block, a first low-potential liner and a common potential line, and the line-changing connection block is electrically connected with the first gate line and the second gate line through via holes respectively; at least part of the first low-potential liner is locatedbetween the line-changing connection block and the common potential line, and the potential of the first low-potential liner is lower than the potential of the common potential line and lower than thelowest potential of the line-changing connection block. According to the invention, the line-changing connection block area in the display panel can be protected from being corroded.

Description

technical field [0001] The present invention relates to the technical field of display, and more specifically, to a display panel and a display device. Background technique [0002] The display panel is an important part of the display device, and plays a role of providing image display for the display device. Generally, the display panel includes a display area and a frame area. In the display device, a picture is generated and displayed in the display area, and peripheral circuits are arranged in the frame area, which is not an effective picture display area. As people have higher and higher requirements on display performance and aesthetics of display devices, display devices with narrow borders have become a direction pursued by more and more people. [0003] In order to realize the narrow frame of the display device, a double-layer wiring design of the frame area is currently adopted, and the width of the frame area is reduced by double-layer wiring. The display panel...
