Abstract

The invention relates to a display panel and a display device. The display panel comprises a display area and a non-display area which is at least partially distributed around the display area. The display panel comprises a substrate, a light-emitting element layer, a retaining wall structure, a packaging layer and a fixed voltage signal line, wherein the substrate is provided with a first area corresponding to the display area and a second area corresponding to the non-display area, and the second area includes a driving device forming area, a retaining wall setting area and a peripheral area; the driving device forming area is located between the first area and the retaining wall setting area, and the peripheral area is located on the side, away from the first area, of the retaining wallsetting area; the light-emitting element layer is arranged in the first area; the retaining wall structure is arranged in the retaining wall setting area; the packaging layer is arranged on one side,back to the substrate, of the light-emitting element layer and the retaining wall structure; and the fixed voltage signal line is arranged in the non-display area, the cross section of the fixed voltage signal line stretches across the driving device forming area, the retaining wall setting area and the peripheral area, and the fixed voltage signal line is arranged between the substrate and the packaging layer. The display panel provided by the invention can reduce the voltage drop of the fixed voltage signal line.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the continuous update of display panel technology, the display panel is gradually developing towards thinner and lighter, higher screen-to-body ratio, and ultra-narrow bezel. The display panel usually includes a display area and a non-display area located around the display area. The non-display area is used to arrange signal lines, such as fixed voltage signal lines. As the non-display area of ​​the display panel becomes narrower, the line width of the fixed voltage signal lines located in the non-display area becomes smaller and smaller, resulting in an increase in the voltage drop of the fixed voltage signal lines. [0003] Therefore, how to reduce the voltage drop of the fixed voltage signal line has become an urgent technical problem to be solved by those skilled in the art. Contents of t...
