Abstract: The present application provides a display panel and an electronic device. A first sub-backlight module is arranged in a display area of the display panel, and a second sub-backlight module is arranged in an electronic component area. A light guide plate of the second sub-backlight module can be switched between a light-scattering state and a transparent state, so that the electronic component area can display images and take photos. The first light-shielding member is arranged in an accommodating space defined by the display panel body and the backlight module to avoid light leakage during shooting, so that full-screen display can be realized without light leakage.
