Abstract
An electronic device can include an organic device layer having a first and a second portion. In one embodiment, the first portion can have a higher resistivity than the second portion and lie between a first and a second electrode and include not more than 15 mole percent basic material. In a particular embodiment, the first and the second electrode can be an anode and cathode of a pixel. In another particular embodiment, the first and the second electrode can be either both anodes or both cathodes of different pixels. In another embodiment, the organic device layer can include a large molecule material. In still another embodiment, a process of forming the electronic device can include selectively modifying the first portion of the organic device layer.
