PROBLEM TO BE SOLVED: To provide an organic thin film EL element with high brightness and stable illumination which enables to obtain an arbitrary luminous colors within a range of green to orange. SOLUTION: The organic thin film EL element using a polimethene compound comprising at least one layer of a hole carrier layer 4 composed of organic compound and an electron carrier layer 5 between a pair of electrodes 2, 7, is characterized by the fact that the hole carrier layer or the electron carrier layer is doped with at least one kind of polymethene compound shown by the formula (1), where; R1-R12 are selected from hydrogen atom, alkyl group, or aryl group, and R13-R14 are selected from benzene ring or aromatic fused ring.
