Abstract
An organic light-emitting device, comprising: a substrate; a first conductive layer formed over the substrate; at least one layer of a light-emissive organic material formed over the first conductive layer; a barrier layer formed over the at least one organic layer which acts to protect the at least one layer of organic material; and a second conductive layer, preferably a patterned sputtered layer, formed over the barrier layer.
Claims106
An organic light-emitting device, comprising:
- a substrate;
- a first conductive layer formed over the substrate;
- at least one layer of a light-emissive organic material formed over the first conductive layer;
- a barrier layer formed over the at least one organic layer which acts to protect the at least one layer of organic material;
- and
- a patterned second conductive layer formed over the barrier layer.
A method of fabricating an organic light-emitting device, comprising the steps of:
- forming a first conductive layer over a substrate;
- forming at least one layer of a light-emissive organic material over the first conductive layer;
- forming a barrier layer over the at least one organic layer;
- and
- forming a patterned second conductive layer over the barrier layer;
- wherein the barrier layer acts to protect the at least one organic layer during subsequent processing steps.
