Abstract: A display panel and an electronic device are provided. The electronic device includes the display panel. The display panel includes a display panel main body, a protective layer, a light source module, and a light sensor. Outgoing light emitted by the light source module can be totally reflected in the protective layer. When a finger touches an area of the protective layer corresponding to a display area, light emitted to the finger can be reflected to light sensor. As such, a range of under-screen fingerprint recognition can be increased.
