PURPOSE: Provided is an organic electroluminescence display device comprising a compound having high melting point, and excellent hole transportation and heat stability as a hole transportation layer. CONSTITUTION: The organic electroluminescence comprising an organic layer inserted between an anode and a cathode on a board, is characterized in that the organics layer comprises a hole-transportation layer containing a compound represented by formula 1(wherein each of R1 and R2 is selected from the group consisting of hydrogen(H), alkyl group, alkoxy group, halogen group, aryl group, or substituted aryl group). The organics layer is a multilayer construction consisting of hole-injection layer, hole-transportation layer, light emitting layer, electron transportation layer, and electron injection layer. |
