Abstract:
1. A liquid crystal display (LCD) device, comprising: a first substrate; a color filter formed on the first substrate, for implementing RGB colors by forming, in first to third metal layers, first to third sub-wavelength holes each having a different period, wherein the metal layers having the sub-wavelength holes are used as the color filter using a surface plasmon occurring from the metal layers, and wherein each thickness of the metal layer corresponding to each color is differently controlled; an insulating layer formed on the metal layers including an inside of the sub-wavelength holes and formed of a same dielectric material as that of the first substrate; a thin film transistor formed on the insulating layer; and a second substrate bonded to the first substrate with facing the first substrate, wherein first to third sub-color filters of the color filter are tangent to one another in a hexagonal shape, and lines connecting centers of the first to third sub-color filters to one another form a triangle.
