  • Patent number: 8143771
    Abstract: A filter for a display device includes a base substrate, a shielding film formed based on a single transparent base layer, and an adhesive layer adhering the shielding film onto the base substrate. The shielding film which realizes diverse shielding functions in a single sheet is adhered onto the base substrate through a single process, which serves to improve productivity, reduce manufacturing cost, restrain the occurrence of Haze and improve visibility.

  • Publication number: 20090058250
    Abstract: A filter for a display apparatus is placed in front of a display panel, wherein CIE chromaticity coordinates of the filter under a standard of a D65 light source have values of ?2.0?a*?2.0 and ?2.0?b*?2.0. The CIE chromaticity coordinates of the filter under the standard of the D65 light source have a value of 60?L*?80. The colorants include a first colorant absorbing 380 nm to 480 nm wavelength light, a second colorant absorbing 450 nm to 550 nm wavelength light, and a third colorant absorbing 560 nm to 620 nm wavelength light. The first to third colorants can be contained in at least one of a color compensating layer, a low-refraction layer having a refractive index of 1.5 or less, an external light shielding layer, a hard coating layer and an adhesive layer.
