Abstract
Official abstract text for this publication.
An organic EL display includes: lower electrodes arranged on a substrate to correspond to first organic EL elements of blue and second organic EL elements of any other color, respectively; hole injection/transport layers arranged on the lower electrodes; second organic light-emitting layers of the other color arranged on the hole injection/transport layers for the second organic EL elements; a first organic light-emitting layer of blue arranged on whole surfaces of the second organic light-emitting layers and the hole injection/transport layers for the first organic EL elements; an electron injection/transport layer arranged on a whole surface of the first light-emitting layer, the electron injection/transport layer made of a nitrogen-containing heterocyclic compound with an electron mobility of 1.0×10 −6 cm 2 /Vs to 1.0×10 −1 cm 2 /Vs both inclusive and having one or both of electron injection properties and electron transport properties; and an upper electrode arranged on the electron injection/transport layer.
First claim
Opening claim text (preview).
What is claimed is: 1. An organic EL display comprising: lower electrodes arranged on a substrate to correspond to (i) first organic EL elements for blue light, and (ii) second organic EL elements for light of a color or colors other than blue; hole injection/transport layers arranged on the lower electrodes to correspond to (i) the first organic EL elements, and (ii) the second organic EL elements, the hole injection/transport layers having hole injection properties and/or hole…
