Abstract: PROBLEM TO BE SOLVED: To improve the hole filling performance and electron filling performance, save the power consumption, and prolong the lifetime by having a hole filling layer between a positive electrode and a hole transport layer, and having an electron injection layer between a negative electrode and an electron transport layer. SOLUTION: In an EL element, direct current voltage is applied between a positive electrode 2 and a positive electrode 4 so that hole, which is filled from the positive electrode 2 through a hole filling layer 11, arrives a light emitting layer 7 through a hole transport layer 6 and so that electron, which is injected from the negative electrode 4 through an electron injecting layer 12, arrives the light emitting layer 7 through an electron transport layer 8. As a result, in the light emitting layer 7, recombination of the electron/hole is generated so as to generate the singlet exciton, and the light emission having the predetermined wavelength is generated. In the case of a layer structure (b), in which the light emitting layer is omitted, the light emission having the predetermined wavelength is generated from an interface of the hole transport layer 6 and the electron transport layer 8. These light emission is observed from a substrate 1 side. In the case of a transmission type EL element expressed with a figure (a), light emission can be observed from a protecting layer 5, besides from the substrate 1 side.
