Abstract:
Disclosed herein is an organic electroluminescence display device including: a substrate; a plurality of lower electrodes formed thereon for each of a plurality of organic electroluminescence elements; a plurality of hole injecting/transporting layers capable of either hole injection or hole transportation which are formed on the lower electrodes for each of the organic electroluminescence elements; a plurality of organic light emitting layers containing a low-molecular weight material which are formed on the hole injecting/transporting layers for each of the organic electroluminescence elements; an electron injecting/transporting layer capable of either electron injection or electron transportation which is formed over the entire surface of the organic light emitting layers; and an upper electrode formed on the electron injecting/transporting layer.
