Abstract
A display panel and a display device are provided. In an embodiment, the display panel includes: a substrate; a plurality of metal parts disposed above the substrate; and a plurality of light-emitting elements disposed at a side of the plurality of metal parts facing away from the substrate, each of the plurality of light-emitting elements including a first electrode, a light-emitting portion, and a second electrode stacked in sequence in a light-exiting direction of the display panel. In an embodiment, an orthographic projection of each of the plurality of metal parts on the substrate covers an orthographic projection of a respective one first electrode on the substrate. In an embodiment, the first electrode has a relatively flat surface, so the probability of mutual interference between the ambient light reflected by the first electrode is reduced, which can alleviate color dispersion of the display panel in a dark state.
