Display panel and display device

Abstract

The application provides a display panel and a display device. The display panel comprises a substrate layer, a first conductive pattern and a second conductive pattern. The first conductive pattern and the second conductive pattern are both located on the substrate layer and are insulated from each other. The orthographic projection of the first conductive pattern on the substrate layer is arranged apart from the orthographic projection of the second conductive pattern on the substrate layer. The first conductive pattern forms a radiating antenna. At least one of the side of the first conductive pattern close to the second conductive pattern and the side of the second conductive pattern close to the first conductive pattern has a plurality of free ends. No current flows between two adjacent free ends, so that the radiated energy at the free ends is low, thereby reducing the coupling energy between the first conductive pattern and the second conductive pattern. Therefore, the display panel and the display device provided by the embodiments of the application can reduce the interference between the first conductive pattern and the second conductive pattern, thereby improving the antenna performance and the signal transmission performance of the display panel and the display device.
