Embodiment Construction

[0055] The present invention will now be described in detail with reference to the accompanying drawings.

[0056] For brief description with reference to the drawings, the same or equivalent components will be given the same reference numerals, and descriptions thereof will not be repeated.

[0057] Hereinafter, a color filter using surface plasmons, a liquid crystal display (LCD), and a manufacturing method thereof according to the present invention will be explained in more detail with reference to the accompanying drawings.

[0058] The conventional method of increasing the light transmittance of the LC panel by increasing the aperture ratio of the array substrate has many limitations. Therefore, it is necessary to change the conventional style into a new style that improves light transmittance of the LC panel by removing the color filter.

[0059] To this end, a light filtering method has been proposed in which light of a specific wavelength can be selectively transmitte...

Abstract

The present invention relates to a color filter using surface plasmons, a liquid crystal display (LCD) device and a method for fabricating the same. Through forming a transmissive pattern which is composed of a plurality of sub-wavelength holes having a period on a metal layer for selectively transmitting the light with a certain wavelength, the transmittance of a LC panel can be improved and a whole process can be simplified. There is provided a color filter using surface plasmons, comprising: the metal layer; the transmissive pattern formed in the metal layer, and consisting of a plurality of sub-wavelength holes having a period; and a plurality of non-penetrating grooves formed at a region encompassing the plurality of holes, wherein a desired color is implemented by selectively transmitting light of a specific wavelength by using surface plasmons. A plurality of grooves with the period is formed on an area with a plurality of holes thereby realizing the light beam with extraordinarily narrow radiation angle. Thus the correlation between a wavelength of a main peak of the transmitted light and a visual angle can be improved. Furthermore the transmittance and calibration are improved.

Description

technical field [0001] The present invention relates to a color filter using surface plasmons, a liquid crystal display (LCD) and a manufacturing method thereof, and more particularly, to a color filter using surface plasmons and having an A color filter of a three-dimensional (3D) pattern structure of a light-transmitting pattern, an LCD, and a manufacturing method thereof. Background technique [0002] With increasing interest in information displays and increasing demand for portable information media, research and commercialization of flat panel displays (FPDs) that replace conventional display devices such as cathode ray tubes (CRTs) are actively being conducted. As one of these flat panel displays, a liquid crystal display (LCD) displays images by using optical anisotropy of liquid crystals (LC). Due to excellent resolution, color reproduction characteristics, and image quality, LCDs are being actively used in notebooks, desktop monitors, and the like. [0003] The L...
