  • Patent number: 8593595
    Abstract: Discussed are a color filter using a surface plasmon and a liquid crystal display (LCD) device, the color filter capable of enhancing a transmittance ratio of an LC panel by having a 3D pattern structure of a transmissive pattern for selectively transmitting light of a specific wavelength, and capable of simplifying entire processes. According to the color filter using a surface plasmon and the LCD device, not only three colors of RGB but also multi-colors can be implemented, and color reproduction can be enhanced by optimizing arrangement of the transmissive pattern according to the number of colors to be implemented.

  • Patent number: 8379171
    Abstract: Discussed are an FFS mode LCD device capable of enhancing a transmittance ratio by including a color filter of a three-dimensional pattern structure having a transmissive pattern for selectively transmitting light of a specific wavelength by using a surface plasmon phenomenon, and a method for fabricating the same. The metal layer using a surface plasmon is utilized as a common electrode of the array substrate, and the pixel electrode having slits is formed on the metal film, thereby generating a fringe field. This may simplify the entire processes, and remove color filter processing lines, thereby reducing the installation costs.
