Title:
ORGANIC ELECTROLUMINESCENCE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2002/052905
Kind Code:
A1
Abstract:
An organic electroluminescence element characterized by having, between an anode and a cathode, one or more organic thin film layers containing luminous zones consisting of one or more luminous layers, and containing in at least one organic thin film layer a compound represented by one of the following formulae [I], [II], [III]. The organic EL element can restricts light emission from layers other than the luminous zones (luminous layers), and is high in color purity of a luminescent color, luminance, and luminous efficiency.
