PURPOSE: A pyridine derivative compound is provided to have high triplet energy(T1), and to have excellent luminous efficiency like high thermal stability, and to have low driving voltage, luminance, color purity, and long life time. CONSTITUTION: A pyridine derivative compound is in chemical formula 1. An organic electroluminescence device comprises an anode, a cathode, and a layer inserted between the cathode and the anode, and a layer comprising the pyridine derivative compound. The pyridine derivative is contained in an electroluminescent layer between the anode and the cathode. One or more layers selected from a group consisting of a hole injection layer, a hole transport layer, an electron block layer, a hole block layer, an electron transport layer, and an electron injection layer is additionally comprised between the anode and the cathode. |
