摘要：
A display with organic electroluminescent elements each having an optical-interference structure includes; a blue-light emitting layer containing a host material and a light emitting material, where lowest unoccupied molecular orbital of a hole-transporting layer is smaller than that of the host material and highest occupied molecular orbital (HOMO) of the host material is larger than that of the hole-transporting layer by 0.5 eV or lower; and a film-thickness adjustment layer disposed between a light emitting layer and the hole-transporting layer of a red-light emitting electroluminescent element or a green-light emitting electroluminescent element, where the hole-mobility of the adjustment layer is higher than the carrier-mobility of the light emitting layer of the electroluminescent element having the adjustment layer, and HOMO of the adjustment layer is not higher than that of the hole-transporting layer and not lower than that of the light emitting material in the light emitting layer thereof.
