Abstract: A display device and an electronic device are provided. The display device includes a back plate, a display panel, an optical film, a first light-emitting unit, and a second light-emitting unit. The display panel and the second light-emitting unit are carried on the back plate. The optical film and the first light-emitting unit located on one side of the optical film away from the display panel are accommodated in an accommodating cavity cooperatively defined by the display panel and the back plate. The visible light emitted by the first light-emitting unit is incident on the display panel via the optical film. A part of the ultraviolet light emitted by the second light-emitting unit avoids the display screen and is emitted onto the transparent cover plate, and another part of the ultraviolet light is emitted onto the transparent cover plate via the display screen, to clean the display panel.
