  • Publication number: 20120013978
    Abstract: The present invention relates to a pressure sensitive adhesive film for an orientating treatment of a photo-orientable layer, a laminated film, a method for preparing an optical filter or a stereoscopic image display device. In the present invention, the pressure sensitive adhesive film for an orientating treatment in a photo-orientable layer which can minimize the generation of the un-orientated regions, and can form the orientated pattern having high degrees of accuracy, and the preparation method for an optical filter using the pressure sensitive adhesive film are provided. Further, the present invention can provide the optical filter and the stereoscopic image display device having excellent performance.

  • Patent number: 6714272
    Abstract: Even though a conventional color LCD device further includes an extra element such as a color filter for color display, the present invention does not need the extra element. The liquid crystal layer is initially aligned parallel to the substrates and then re-aligned by the applied voltage. Transmittance for the specific wavelength is changed according to an angle between the transmission axis of the liquid crystal layer and the light axis of the polarizer. Thus, multiple colors or full color can be realized without the extra element for color display. Therefore, the transmittance of the LCD device is improved and the cost for the LCD device is reduced.
