PURPOSE: An organic light emitting material composition is provided to improve luminous efficiency and luminescent brightness of an organic electroluminescent device and to increase life span of devices. CONSTITUTION: An organic light emitting material composition is used as a light emitting material of an organic electroluminescent device and comprises a polyphenyl benzene derivative represented by chemical formula I. In chemical formula I, R1-R3 are hydrogen or substituted or unsubstituted 6-30 nucleus carbon atoms-containing aryl group. The organic electroluminescent device includes at least one organic layer cont including the organic light emitting material composition. |
