Organic EL elements provided with a substrate 10 , a first electrode layer 12 and a second electrode layer 18 situated in a mutually opposing manner on one side of the substrate 10 , and a luminescent layer 20 situated between the electrode layers, wherein one of the first electrode layer 12 and the second electrode layer 18 is a hole injection electrode layer and the other is an electron injection electrode layer, and there is formed in the luminescent layer 20 a modified section 16 which contains an organic polymer compound different from the organic compound composing the luminescent layer 14 , in bias toward the electron injection electrode layer. |
