Abstract:
1. A surface plasmon display device comprising: a first substrate and a second substrate which form a space in which electrophoretic particles including metal particles are included; an electrode structure including a first electrode and a second electrode respectively formed on the first substrate and the second substrate; a plurality of pixel regions that can be electrically addressed by the electrode structure; and a dielectric layer formed on an inner surface of the first substrate to correspond to each of the pixel regions to generate a surface plasmon resonance with the metal particles, wherein the dielectric layer in each of the pixel regions has physical properties which cause the surface plasmon resonance corresponding to a wavelength designated to a corresponding pixel region of the plurality of pixel regions, the second electrode includes a plurality of sub-electrodes corresponding to each of the pixel regions and the dielectric layer includes a plurality of sub-dielectric layers corresponding to each of the sub-electrodes, wherein the sub-electrodes are independent from each other and the sub-dielectric layers are independent from each other.
