ABSTRACT:
The present invention discloses a hole transport layer of an organic EL display, comprising: a material including one of a PEDOT which is a mixture of a poly (3,4)-ethylenedioxythiophene and a polystyrenesulfonate, a PANI which is a mixture of a polyaniline and a polystyrenesulfonate, and an aromatic amine derivative; and an organic compound derivative having the general structure, R1R2MR3R4, where “M” denotes one metal selected from a group consisting of Ti, Pt and one metal among elements belonging to groups 3A and 4A of periods 3 to 5.
