  • COLOR FILTER AND LIQUID CRYSTAL DISPLAY DEVICE
    Publication number: 20130242238
    Abstract: A color filter includes at least one blue color resist so that a blue light with a Y coordinate that is about 0.045˜0.051 in the CIE chromaticity diagram is generated when light passes through the blue color resist. Furthermore, a liquid crystal display device employing the color filter is also disclosed herein.

  • FILTER UNIT OF LIQUID CRYSTAL DISPLAY AND LIQUID CRYSTAL DISPLAY
    Publication number: 20130155355
    Abstract: A filter unit of a LCD and a LCD are provided. Under a CIE standard C light source, an x-coordinate value of light passing through the filter unit in a CIE 1931 chromaticity coordinate is greater than or equal to 0.302, an illumination Y value of the light is greater than or equal to 60, and relative to the standard color sample in which (x, y) is (0.299, 0.595) in a CIE 1931 chromaticity coordinate, the CIE DE2000 color difference value ?E00 of the light is less than 1.

  • COLOR FILTER AND LIQUID CRYSTAL DISPLAY
    Publication number: 20130128195
    Abstract: Disclosed herein is a color filter, which includes a substrate and a green color resist. The green color resist is disposed on the substrate. The green color resist has a function A(?) defined by a product of the transmittance spectrum of the green color resist and the CIE color matching function Z(?). The function A(?) has a maximum of less than 0.28, and the function A(?) satisfies the following formula (II): ?380780A(?)d?>10.26??formula (II).

  • BLUE PHOTORESIST AND COLOR FILTER SUBSTRATE AND DISPLAY DEVICE USING THE SAME
    Publication number: 20120275045
    Abstract: A blue photoresist for a color filter substrate is provided. In the wavelength 380 nm to 580 nm, the half-width of the spectrum function of the blue photoresist is represented as Ha, the half-width of the color match function defined by CIE (Commission International de L'Eclairage) at 1931 is presented as Hb, and 3.7>Ha/Hb>1.91. Therefore, the light transmittance of the blue photoresist can be improved so that the efficiency utilizations of light of a color filter substrate and display device using the blue photoresist are provided.
