Embodiments of the present invention provide a display panel and a display device, which relate to the field of display technology, and can reduce the equivalent resistance of the cathode signal line and the cathode connection, thereby reducing the decrease in the cathode voltage at a position far from the signal source, and improving The adverse effect on the display effect caused by this is eliminated. The display panel includes: a cathode signal line, an insulating layer and a cathode layer which are sequentially stacked in a direction perpendicular to the display panel; the cathode signal line includes a plurality of first hollow areas; the insulating layer includes a corresponding to each first hollow area The insulating part; the orthographic projection of each insulating part on the plane where the cathode signal line is located covers the corresponding first hollow area; the display panel includes a cathode layer connection area, and the insulation layer is located outside the cathode layer connection area. In the cathode layer connection area, the cathode The signal line is in contact with the cathode layer, and in the connection area of the cathode layer, the cathode signal line has protrusions and / or grooves facing one side of the cathode layer.
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] The organic light-emitting display device is also called (Organic Light-Emitting Diode, OLED) organic light-emitting diode display device. Compared with the liquid crystal display device, it has the advantages of lightness, lightness, and large viewing angle. In an OLED display device, an organic light-emitting device is provided. The organic light-emitting device includes a stacked anode, an organic light-emitting layer, and a cathode. Combination light emission in the organic light-emitting layer, wherein the cathode is arranged on the entire surface of the display area, and simultaneously serves as the cathode of multiple organic light-emitting devices. In order to provide the cathode voltage signal to the cathode, it is necessary to connect the cathode signal line to the cathode, and transmit the ca...
