We here firstly present a novel?plasmonic chromic-electrode (PCE) which also works color filter as well as an electrode with low resistivity. We used aluminum (Al) with high plasma frequency for the plasmonic material, and utilized indium-tin-oxide (ITO) for the conducting dielectric material. Finite-difference time-domain (FDTD) analysis was conducted to design a structure with the optimized optical property. The PCE fabricated by laser interference lithography showed red color with 32% transmittance. It also resulted in a sheet resistance of less than 2 ohm/sq which is comparable to that of conventional electrodes. The proposed convergence of an electrode with a chromatic function could contribute to reducing the number of components and simpifying the structure of industrial imaging devices such as displays and image sensors
