An organic electroluminescent device including at least one organic thin
film layer interposed between an anode and a cathode, the at least one
organic thin film layer including a luminescent zone having at least one
luminescent layer, wherein the organic thin film layer contains a compound
represented by one of the following general formulae [I], [II], and [III]:
A.sub.1 -X.sub.1 -(A.sub.2).sub.a [I]
X.sub.N -(Y).sub.n [II]
Y.sub.1 -Y.sub.2 [III]
Since the light emission from layers other than the luminescent zone
(luminescent layer) is significantly decreased in this organic EL device,
the color purity of the light emitted by the device is improved, thus
providing a highly efficient, high luminance organic electroluminescent
device.
