    摘要： A novel derivative of heterocyclic compound having nitrogen atom with a structure made by bonding special groups to benzimidazole, a material for an organic electroluminescence (EL) device comprising the derivative of heterocyclic compound having nitrogen atom and an organic electroluminescence device comprising at least one organic compound layer containing a light emitting layer sandwiched between a pair of electrodes, wherein the device contains the derivative of heterocyclic compound having nitrogen atom. An organic EL device achieving elevation of luminance and of efficiency in light emission even under low driving voltage is obtainable by an employment of the derivative of heterocyclic compound having nitrogen atom for at least one layer composing organic compound layers of the EL device.
