Abstract: An electronic device able to show light graphic includes a housing, plural light-transmissive plates stacked inside the housing, plural light sources disposed inside the housing, and a control unit disposed inside the housing. Each of the light-transmissive plates includes a light-incident surface, a light output surface and an optical pattern formed on the light output surface thereof. Projection zones of the light output surfaces to the light-transmissive region are overlapped. The light sources are respectively arranged for emitting lights towards the light-incident surfaces. The control unit is electrically connected to the light sources for controlling at least one of the light sources to emit lights towards the light-incident surface of the corresponding light-transmissive plate, so that the lights form a light graphic by the optical pattern of the corresponding light-transmissive plate, and the light graphic is shown on a light-transmissive region.
