An organic electroluminescent device capable of blue emission with a high color purity, and a display unit capable of full-color display with high color expressivity by using the organic electroluminescent device are provided. The organic electroluminescent device includes at least a hole transportation layer and a luminescent layer held between a lower electrode to become an anode and an upper electrode to become a cathode in a state of lamination in that order from the anode side. The luminescent layer is made of a spiro compound, and the hole transportation layer is made of triphenylamine tetramer. Furthermore, the display unit includes organic electroluminescent devices as blue-emitting elements arrayed for a plurality of pixels. |
