PURPOSE: To provide a new EL element by forming a laminate of one or more organic layers, and forming one or more organic layers with bridging led by heat and radiation, and forming each layer so that one kind or more charge transporting compounds exist therein. CONSTITUTION: A base electrode 2, a hole-filling layer 3, a hole-transporting layer 4, an emitter layer 5, an electron-transporting layer 6, an electron-filling layer 7, and Al top electrode 8 are laminated on a transparent glass board 1, and a contact 9 is provided, and they are covered with a capsule 10. A third aromatic amine and perylene are a compound having a group, to which cationic polymerization or radical polymerization can be performed or to which light can be added, and these are led to the layers 3, 4, 6, 7, and the net-like composition of insoluble polymer is formed by bridging led by heat and radiation. With this structure, all the compounds for transporting charges in an arbitrary form can be used as a charge-transporting compound inside of the layers. As an appropriate compound especially for a component of an emitter layer, namely, for a fluorescent dye, a compound having a group, to which anionic, cationic and radial polymerization can be performed, is used.
