PROBLEM TO BE SOLVED: To provide an organic thin film EL element showing excellent light emission characteristics and having excellent durability using a high polymer material. SOLUTION: This organic thin film EL element is provided with a light emitting layer composed of at least one layer of organic compound thin film between the opposing anode and cathode, and at least one layer of the light emitting layers has electric charge carrier performance expressed by the formula (1) as a constituent component and contains aromatic polycarbonate resin having excellent resistance against heat. This organic thin film EL element shows excellent light emission characteristics and durability by using this resin. Wherein, Ar1 and Ar2 are each substituted or non-substituted allylene groups, Ar3 is a substituted or non-substituted allyl group, Z represents an allylene group or -Ar4 -Za-Ar4 -, Ar4 represents a substituted or non-substitute allylene group, Za represents single bond, oxygen atom, sulfur atom or alkylene group, Z1 represents oxygen atom or sulfur atom, and n denotes 0 or 1.
