Abstract

본 발명은 액정표시소자의 구조 개선에 관한것으로 레드(Red), 그린(Green), 블루(Blue) 파장에 대한 셀갭을 설정한 후 R,G,B 칼라필터를 각각의 셀갭후면에 부착하여 콘트라스트를 향상시킬 수 있도록 한 것이다.The present invention relates to the improvement of the structure of a liquid crystal display device. After setting cell gaps for red, green, and blue wavelengths, R, G, and B color filters are attached to the back surface of each cell gap for contrast. To improve it.

이를 위해 본 발명은 R,G,B의 각 파장에 대한 셀갭의 성정은 물론 칼라 필터층(12)을 각 셀갭후면에 설치하여 광의 온/오프비 즉, 쿤트라스트를 향상시킬 수 있도록 한 것이다.To this end, the present invention is intended to improve the on / off ratio of light, that is, the tunability, by providing the color filter layer 12 on each cell gap back surface as well as the determination of the cell gap for each wavelength of R, G, and B.
