ORGANIC LIGHT EMITTING DIODE CONTAINING METALLOCENE COMPOUNDS CAPABLE OF DECREASING DRIVING VOLTAGE AND IMPROVING LUMINOUS EFFICIENCY BY IMPROVING ELECTRON INJECTION PROPERTY, AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: An organic light emitting diode is provided to decrease driving voltage and to improve luminous efficiency by inserting an interfacial layer containing metallocene compounds between a negative electrode and electroluminescent layer.;CONSTITUTION: An organic light emitting diode comprises: a positive electrode and a negative electrode corresponding each other; an electroluminescent layer between the positive electrode and the negative electrode; and a first interfacial layer between the electroluminescent layer and the negative electrode. The first interfacial layer comprises metallocene compounds in the chemical formula 1. In the chemical formula 1, M is a transition metal, R^1-R^10 is respectively hydrogen, hydroxy group, halogen, or C1-C20 saturated or unsaturated hydrocarbon group capable of containing one or more hero atoms selected from B, Al, Si, O, S, N and P. X^1 and X^2 is respectively halogen group.;COPYRIGHT KIPO 2012
