PURPOSE: A dibenzochrysene derivative compound is provided to have excellent driving voltage, current efficiency, etc, thereby capable of improving driving voltage of a device and luminous efficiency. CONSTITUTION: A dibenzochrysene derivative compound is represented by chemical formula 1. An organic electroluminescence device comprises an anode, a cathode, and the dibenzochrysene derivative compound between the anode and the cathode. The dibenzochrysene derivative compound is comprised in a light-emitting layer between the anode and the cathode. One or more layer consisting of a hole injection layer, a hole transport layer, an electron block layer, a hole block layer, an electron transport layer, an electron injection layer is comprised between the anode and the cathode.
