ABSTRACT:
A color filter formed in accordance with the invention is formed by depositing a thin film of organic pigment an on electrode by electrochemical methods. An organic pigment is included in an aqueous micellar solution that includes a surfactant that has redox reactivity. The surfactant preferably has a metallocene such as ferrocene at the hydrophobic terminal end group. A transparent substrate having a transparent electrode thereon is emersed in the micellar solution. Voltage is applied to the transparent electrode and the organic pigment will form on the transparent electrode. Conductive particles, polymer material or conductive polymer material can be included with or on the pigment. Alternatively, the polymer or conductive polymer can be layered.
