ABSTRACT:
The present invention is an organic EL device in which an anode, a hole injection layer, a first carrier transportation layer, a first luminescent layer, a second carrier transportation layer, a second luminescent layer, an electron transportation layer, and a cathode are formed on a glass substrate in order, wherein layers with a smaller electron affinity Ea and a larger energy gap Eg than those of the first and second luminescent layers are employed for the first and second carrier transportation layers, so as to enhance the emission efficiency of the first and second luminescent layers.
