Page/Page column 85, (2008/06/13)
A specific derivative of heterocyclic compound having nitrogen atom and an organic electroluminescence device comprising the compound. An organic electroluminescence device comprising at least one of organic compound layers including a light emitting layer sandwiched between an anode and a cathode, wherein said at least one of the organic compound layers comprises the derivative of the heterocyclic compound having nitrogen atom as a sole component or as mixed component. The organic electroluminescence device achieves elevation of luminance and excellent efficiency of light emission, and also achieves long lifetime by an improvement of an electrode adhesion.
