| Abstract: | This paper describes reviews about the characterization of optical and electronic (opto-electronic) organic materials including polymers, and their applications for advanced key devices used for computers and communications technologies. On the basis of the author's recent investigations, discussions are made on organic electroluminescent thin film materials for emissive display devices, polymer-dispersed liquid crystal materials for passive display devices, organic photo-conductive materials for electrophotographic printer devices, and highly electroconductive polymers for solid tantalum capacitors. Finally, technical issues and development prospects for the opto-electronic organic materials in the 21st century are suggested. |
