Abstract

A display panel and a display device are described. In an embodiment, the display panel includes a first through-hole, a second through-hole, and a third through-hole that are provided in a display region. In an embodiment, a first non-display region surrounds the first through-hole and the second through-hole, and a second non-display region surrounds the third through-hole. In an embodiment, a minimum distance between the first through-hole and the second through-hole in a first direction is smaller than a minimum distance between the second through-hole and the third through-hole in the first direction. In an embodiment, the display region has a symmetry axis extending along a second direction. In an embodiment, the symmetry axis overlaps with the second through-hole, or is located between the second through-hole and the third through-hole. Thus, the overall symmetry of the display region is improved.
