ORGANIC ELECTROLUMINESCENT ELEMENT USING POLYARYLAMINE

摘要

This invention provides an organic electroluminescent element using polyarylamine, comprising one or more organic compound layers held between a pair of electrodes comprising an anode and a cathode, wherein the organic compound layer comprises a hole transport layer and/or a hole injection layer, and a polyarylamine having a specific structure is contained in the hole transport layer and/or the hole injection layer. The organic electroluminescent element can particularly realize simplification of the production process, an increased screen size, and improved element properties.
