Abstract

Embodiments of the present disclosure disclose a display panel, which includes a cover plate, a pixel layer, and a driving circuit layer. The driving circuit layer is disposed between the cover plate and the pixel layer. The driving circuit layer includes a metal layer and a darkening layer, the darkening layer is disposed on a side of the metal layer towards the cover plate, and a reflectivity of the darkening layer of external light is less than a reflectivity of the metal layer of the external light. When the external light is irradiated, the reflectivity of the darkening layer is less; therefore rainbow mura generated when the external light source illuminates the display panel.
