An organic electroluminescent element comprising a substrate, a pair of electrodes including an anode and a cathode, disposed on the substrate, and at least one organic layer which is arranged between the electrodes and which includes a light emitting layer, wherein the organic layer contains a compound represented by general formula (1) in at least one layer. The organic electroluminescent element has a high luminous efficiency, excellent blue color purity, and little chromaticity change due to drive deterioration. (In the formula, the two Xs either both represent an O atom or both represent an S atom, and R1-R10 each independently represents a hydrogen atom or a substituent group).
一种有机电致发光元件,包括基板、一对电极包括阳极和阴极,设置在基板上,并且至少包括一个有机层,该有机层位于电极之间并包括一个发光层,其中该有机层至少包含一层由通式(1)表示的化合物。该有机电致发光元件具有高发光效率、优异的蓝色纯度和由于驱动恶化引起的色度变化较小的特点。(在式子中,两个X代表O原子或S原子,R1-R10各自独立地表示氢原子或取代基)。
