  • POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY HAVING THE SAME
    Publication number: 20150268509
    Abstract: A liquid crystal display includes: a liquid crystal panel which displays an image on a surface thereof; two polarizing films disposed on opposing surfaces of the liquid crystal panel, respectively; two compensation films disposed between the liquid crystal panel and the two polarizing films, respectively; two protective films disposed on outer surfaces of the two polarizing films, respectively, and an anti-glare layer disposed on the two protective film in a direction of displaying the image.

  • Polarizing plate comprising a compensation film having a first retardation value Rand a second retardation value Rand liquid crystal display having the same
    Patent number: 8958034
    Abstract: A liquid crystal display includes a liquid crystal panel, a polarizing plate on a surface of the liquid crystal panel and having a polarizing axis; and a compensation film between the liquid crystal panel and the polarizing plate, and having an optical axis at which light passes through the compensation film. When a surface of the compensation film is referred to as a x-y plane, a plane passing through an x-axis and vertical to the optical axis of the compensation film is referred to as an x-y? plane. A first retardation value (Ro?) of the compensation film is (nx?ny?)d, and a second retardation value (Rth?) is [(nx+ny?)/2?nz?]d, and the first and second retardation values (Ro?) and (Rth?) satisfy the following Formula of 0.92?Rth?/Ro??4.75, where ‘n’ denotes a refractive index and ‘d’ denotes a thickness of the compensation film in a z-axis direction.
