ABSTRACT:
An organic electroluminescent element ("organic EL element") capable of emitting light with high luminance by driving at a low voltage, and inhibiting deterioration in organic layers is provided. A surface treatment of an indiumtin oxide (ITO) transparent electrode with a titanate coupling agent containing phosphorus in the side chain thereof improves adhesion between the ITO transparent electrode and an organic hole transport layer. As a result, it is possible to increase the efficiency of injection of holes, improve low-voltage driving and luminance, and prevent deterioration in the organic layers.
