Patterning of thin films for the fabrication of organic multi-color displays

Organic light emitting devices and methods of making them are described. The devices contain a substrate, a first electrical contact layer, a patterned organic layer, and a second electrical contact layer. A covering portion covers the sides of the organic layer, protecting the same. In the methods,...

Summary:Organic light emitting devices and methods of making them are described. The devices contain a substrate, a first electrical contact layer, a patterned organic layer, and a second electrical contact layer. A covering portion covers the sides of the organic layer, protecting the same. In the methods, a first organic layer is provided over a first electrical contact layer, followed by a patterned second electrical contact layer. The organic layer is etched using the patterned electrical contact layer as a mask. In one embodiment, the etching step exposes an area over the first electrical contact layer, and a second organic layer is provided over the exposed area.
