Among them, the shading portion 310 includes a conductive material, and at least part of the shading portion 310 is reused as an antenna unit. The antenna unit and the filter unit 330 are arranged in the same layer. The radiation energy of the antenna unit is emitted outward from the shading portion 310 without passing through the filter unit 330, thereby reducing the influence of the filter unit 330 on the radiation energy of the antenna unit, improving the signal strength of the antenna unit, and the antenna unit and the filter unit 330 are arranged in the same layer, which is conducive to reducing the film layer, thereby reducing the thickness of the display panel, and improving the performance of the display panel.
