Abstract

The embodiment of the invention provides a display panel and a display device. The display panel comprises a substrate base plate and a flexible packaging layer arranged on the substrate base plate, wherein the flexible packaging layer comprises a first inorganic layer; and a power signal line, a signal connection layer and a first electrode sequentially arranged on the substrate base plate, wherein the signal connection layer is connected with the power signal line and the first electrode. The display panel also comprises an inorganic contact layer arranged between the signal connection layerand the power signal line, wherein the signal connection layer comprises a plurality of via holes, and the first inorganic layer contacts the inorganic contact layer by the via holes. According to the display panel and the display device provided by the invention, through the arrangement of the inorganic contact layer and the via holes formed in the signal connection layer, the first inorganic layer used for packaging contacts the inorganic contact layer by the via holes, and thus the contact force between the first inorganic layer and the display panel is increased, the packaging effect is enhanced, and the risk that the first inorganic layer is peeled off during a flexible bending process is reduced.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] Flexible display panels have attracted more and more attention due to their thin, light and bendable properties. Flexible and foldable is also a key research direction in the field of display technology. Existing flexible display panels use flexible thin film encapsulation (TFE) technology to fabricate inorganic layers and organic layers on the display panel by means of vapor deposition and inkjet printing, respectively. Folding display panels are usually subjected to continuous bending during use, and in the process of repeated bending, due to insufficient contact adhesion between the packaging layer and the display panel, there is a risk of peeling off the flexible packaging layer, which further leads to packaging failure , the display panel is affected by water vapor and oxygen in the air and di...
