发明名称 ORGANIC ELECTROLUMINESCENT DISPLAY ELEMENT
摘要 PROBLEM TO BE SOLVED: To impart translucency as a whole, high luminance and excellent luminous efficiency to an organic electroluminescent display element and to facilitate its manufacturing. SOLUTION: This organic electroluminescent display element is provided with a positive electrode 2, organic luminescent films (3, 4, 5), an electron injection layer 6 and a negative electrode 7. In this case, both the positive electrode 2 and the negative electrode 7 are so formed as to have translucency, and the electron injection layer 6 is formed of an organic metal complex of an alkaline metal or an alkaline earth metal, or an organic metal salt of an alkaline metal or an alkaline earth metal, or formed of an oxide of an alkaline metal or an alkaline earth metal, or a halide of an alkaline metal or an alkaline earth metal, and has translucency.
