Abstract

Disclosed are a display panel and a display device in which one reflective plate has different areas with different light reflectance, such that an average reflectance of the reflective plate is lowered, while a light-emitting element is positioned in an area corresponding to a relatively high reflectance area, so that black reflection visibility can be improved while light efficiency and light reflectance can be optimized. The display panel includes a substrate; a reflective plate disposed on the substrate; and a light-emitting element disposed on the reflective plate, wherein the reflective plate includes a first reflective area and a second reflective area, wherein the first reflective area has a reflectance of light of a wavelength of 550 nm greater than a reflectance of light of a wavelength of 550 nm of the second reflective area, wherein at least a partial area of the light-emitting element overlaps the first reflective area.
