Abstract

An embodiment of the invention provides a display panel and a display device, and relates to the technical field of display. The distance between an organic isolation layer and the edge of a thin filmpackaging layer is increased, and the water oxidation resistance of the display panel is improved. The display panel comprises a display area and a non-display area; a light-emitting element comprising an anode layer, a light-emitting layer and a cathode layer; a driving circuit located in the non-display area; a negative power signal line located between the driving circuit and the display area;a signal transmission line located between the driving circuit and the display area, wherein the signal transmission line is electrically connected to the negative power signal line and the cathode layer respectively; the organic isolation layer covering the area of the signal transmission line not in contact with the cathode layer; the thin film packaging layer covering the display area and thenon-display area.

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] In order to prevent the display device in the display panel from being corroded by water and oxygen, the display film layer can be packaged in a thin-film packaging method at present. Such as figure 1 as shown, figure 1 It is a schematic diagram of a cross-sectional structure of a display panel in the prior art. The display panel includes a display area 1' and a non-display area 2'. The non-display area 2' is provided with a negative power supply signal line 3', a driving circuit 4' and a signal The transmission line 5', wherein the negative power supply signal line 3' is located on the side of the drive circuit 4' away from the display area 1', the signal transmission line 5' is located above the drive circuit 4', and the signal transmission line 5' is used to transmit the negative power supply si...
