Document Type and Number:

Japanese Patent JP3870102

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide an organic luminescent element efficiently emitting light having high brightness.
SOLUTION: This organic luminescent element is composed of a pair of electrodes comprising an anode and a cathode; and at least a layer comprising one or a plurality of organic compounds interposed between a pair of electrodes. At least one layer of the layers containing the organic compounds contains at least one kind of condensation polycyclic compounds represented by formula I. In the formula I, R1, R2, R3, R4 represent each a hydrogen atom, an alkyl group, a substituting or non-substituting alalkyl group, a substituting or non- substituting aryl group, a substituting or non-substituting heterocyclic group, a substituting amino group or cyano group.
