SUBSTRATE FOR PATTERNING ORGANIC THIN FILM, ORGANIC FIELD LIGHT-EMITTING ELEMENT AND ITS MANUFACTURING METHOD, ORGANIC EL DISPLAY, AND ORGANIC EL ILLUMINATION

摘要

PROBLEM TO BE SOLVED: To provide an organic field light-emitting element capable of having low drive voltage and attaining uniform light-emission, wherein it uses a substrate for patterning an organic thin film having a bank formed on a charge transport layer.;SOLUTION: In the substrate for patterning an organic thin film used for the organic field light-emitting element having an electrode layer, and one layer or two layers or more of charge transport layers on the substrate in order, and having a bank on the charge transport layer, and zones partitioned by the bank, a distance A from an interface between the electrode layer and the charge transport layer to an interface between the charge transport layer and the bank at the zone forming the bank on the charge transport layer and a distance B from the interface between the electrode layer and the charge transport layer to the surface of the zone partitioned by the bank on the charge transport layer are different each other.;COPYRIGHT: (C)2010,JPO&INPIT
