Abstract
Official abstract text for this publication.
It is an object of the present invention to provide an organic electroluminescence element which can be easily produced and has a good light-emitting property and a good lifetime property, and a method for producing the same. That is, the present invention provides the organic electroluminescence element comprising an anode, a light-emitting layer and a cathode, and further comprising a metal doped molybdenum oxide layer provided between the anode and the light-emitting layer; and the method for producing the organic electroluminescence element including a stacking step to obtain a metal doped molybdenum oxide layer by simultaneously depositing molybdenum oxide and a dopant metal on another layer which constitutes the element.
First claim
Opening claim text (preview).
The invention claimed is: 1. An organic electroluminescence element comprising: an anode; a light-emitting layer; a cathode; a metal doped molybdenum oxide layer provided between the anode and the light-emitting layer; and a layer that contains a polymer compound on the metal doped molybdenum oxide layer and that has been formed by a wet process, wherein: the metal doped molybdenum oxide layer contains 98% by weight or more of the molybdenum oxide and the dopant metal, and a conte…
