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.
