Abstract
In an organic electroluminescence element which incorporates a substrate having thereon an anode and a cathode and which incorporates a plurality of organic layers between the aforesaid anode and cathode, wherein at least one of the aforesaid organic layers is a first organic layer incorporating a compound having at most 10 repeating units, the first organic layer being prepared by coating the compound having at least one polymerizable group, followed by polymerization.
Claims7
An organic electroluminescence element comprising a substrate having thereon an anode, a cathode and a plurality of organic layers between the anode and the cathode,
- wherein at least one of the organic layers is a first organic layer comprising a first oligomer compound having 2 to 10 repeating units;
- and
- the organic electroluminescence element further comprises a second organic layer comprising a second oligomer compound stacked on the first organic layer, provided that the second oligomer compound has 2 to 10 repeating units;
- and
- the first organic layer is an electron transporting layer and the second organic layer is a positive hole transporting layer.
