In the embodiments of the present invention, a transparent luminous plate and an electron generator are provided. The transparent luminous plate comprises a first transparent electrode plate, a fluorescent powder layer, a cavity layer, and a second transparent electrode plate. The first transparent electrode plate, the fluorescent powder layer, and the cavity layer are sequentially disposed on the second transparent electrode plate. The electron generator is disposed on a lateral side of the cavity layer. Electrons are generated after the electron generator is electrified. The electrons are transmitted into the cavity layer. An electric field E is formed after the first transparent electrode plate and the second transparent electrode plate are electrified.
