Abstract
A display panel and an electronic device are disclosed, and relate to the field of display technologies. An example display panel includes a substrate, and a light emitting diode (LED) mesa and a conductive spreading layer that are located on the substrate. The LED mesa includes a light-emitting surface for emission of light from the display panel. The conductive spreading layer is attached to and fully covers the light-emitting surface.
