Abstract : Light.emitting electroluminescent diodes and electrochemically- driven electroluminescent devices involving conjugated polymers are described. The effect on the properties of polypyrrole films (deposited from aqueous polymerizing solutions of pyrrole) caused by the hydrophilicity/hydrophobicity of the substrate surface is utilized by a "microcontact printing" technique to form patterned liquid crystal display devices.
