Abstract:
A luminous disk provided with a hole, comprising:a disk lamination including a flat substrate, a metallic reflecting layer, and a dye layer; wherein the metallic reflecting layer is formed on one side plane of the substrate and the dye layer is superposed on a side plane of the substrate opposite to the metallic reflecting layer; anda light emitting lamination, superposed on one side of the metallic reflecting layer opposite to the substrate, for emitting light upon reception of an applied external electrical signal, including:an electro-luminescence section having a first side plane and an opposite second side plane, which can luminesce in case the external electrical signal is applied on the first and the second side planes; anda biasing section, comprising a first electrode layer on the first side plane of the electro-luminescence section and a second electrode layer between the electro-luminescence section and the metallic reflecting layer, for receiving and applying the external electrical signal onto the first and the second side planes of the electro-luminescence section.
