Document Type and Number:
Japanese Patent JP4396115
Kind Code:
B2
Abstract:
To provide an organic electroluminescent element drivable at a low voltage and in high luminous efficiency, having good heat resistance and capable of keeping stable luminous characteristics over a long period, in which defect causing short circuit in preparation of an element result from surface roughness of an anode is prevented.
In the organic electroluminescent element, a hole-injecting layer 3 containing a polymer compound having a recurring unit represented by formula (I) and an electron-accepting compound is provided.
