POLARIZATION PLATE AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

Provided is a polarization plate appropriate for an in-plane switching mode liquid crystal display device. The polarization plate can reduce a hue change when an angle-of-view is changed. A liquid display device using the polarization plate is also provided. The polarization plate includes at least: a first protection film, a first polarization film, a second protection film containing a particular cellulose ester as a main content, and a phase difference layer for fixing the orientation of the bar-shaped liquid crystal oriented substantially vertical to the surface of polarization film or the second protection film. These components are arranged in this order. Each retardation between the second protection film and the phase difference layer, retardation in the state that the second protection film and the phase difference layer are layered, and the wavelength dispersion characteristic are in a particular range. An absolute value of the angle defined by the transmittance axis of the polarization film and the in-plane delayed phase axis of the second protection film is in a range from 0 to 1 degree.
