An organic electroluminescent device including at least onenorganic thin film layer interposed between an anode and a cathode, thenat least one organic thin film layer including a luminescent zonenhaving at least one luminescent layer, wherein the organic thin filmnlayer contains a compound represented by one of the followingngeneral formulae [I], [II], and [III]:n [I] A 1 -X 1 -(A 2 ) a [II] X N -(Y) n [III] Y 1 -Y 2 . nSince the light emission from layers other than the luminescent zonen(luminescent layer) is significantly decreased in this organic ELndevice, the color purity of the light emitted by the device is improved,nthus providing a highly efficient, high luminance organicnelectroluminescent device. |
