Abstract: A display panel and a display device are provided. In the first pixel unit region, an orthographic projection of the first light-shielding portion on the base covers an orthographic projection of at least one via hole on the base. Thus, the first light-shielding portion can shield the light which is emitted by the adjacent light-emitting element and reflected by the via hole. In addition, the first light-shielding portion can further shield the light which is emitted by the light-emitting element in the first pixel unit region to the via hole, to avoid reflecting the light to the adjacent pixel unit region by the via hole in the first pixel unit region. Therefore, the light crosstalk between adjacent light-emitting elements is reduced, and the display effect of the display device is improved.
