Abstract

The embodiment of the invention relates to the technical field of display. The invention discloses a display panel and a display device. The display panel provided by the invention comprises a displayarea and a frame area surrounding the display area. The display panel comprises a substrate, and a data line, a first insulating layer, at least two power lines and a second insulating layer are sequentially arranged on the substrate located at the frame area in a stacked mode. The at least two power lines are arranged on the same layer, a spacing area is arranged between the adjacent power lines, and the projection of the spacing area and the projection of the data line on the substrate have an overlapping area. The second insulating layer covers the at least two power lines and fills the spacing area. A covering layer is located on the side, away from the substrate, of the first insulating layer, the covering layer is insulated from at least one power line, and the orthographic projection of the covering layer on the substrate covers the overlapping area. The reliability of the display panel is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technologies, and in particular, to a display panel and a display device. Background technique [0002] As the demand for resolution and brightness uniformity of the display panel is getting higher and higher, 14 masking processes are usually used to prepare the display panel, but the cost of this manufacturing method is relatively high. In order to reduce the manufacturing cost of the display panel and increase the production capacity, 11 masking processes were developed to prepare the display panel. Since 11 masking processes have an absolute advantage over 14 masking processes, most manufacturers currently use 11 masking processes to prepare display panels. However, the traces of the display panel manufactured by applying 11 masking processes have been corroded in the subsequent manufacturing process. Contents of the invention [0003] The object of the embodiments of the pr...
