COMPLEX CONFIGURATION COMPOSITION POLARIZER SET EMBODYING THE CLEAR PICTURE QUALITY BY MINIMIZING THE DISTORTION OF COLOR ACCORDING TO THE TIME

摘要

PURPOSE: A complex configuration composition polarizer set and an in-plane switching mode liquid display device including the same are provide to reduce a dispersion level of polarization state on Poincare sphere, thereby minimizing the distortion of color according to the time.;CONSTITUTION: A front phase difference value of a first phase difference film(24) is 50 to 200nm. A refractive index ratio of a first phase wave film is -1 to -0.01. A ground axis(25) of the first phase difference film is parallel to absorbing axis(22) of neighboring polarizer(21). A front phase difference value of a second phase difference film is 50 to 250nm. A refractive index ration of the second phase difference film is -2 to -0.5. A ground axis of the second phase difference film crosses at right angles to absorption axis neighboring polarizer. The front phase difference values of the first phase difference film and the second phase difference film is 200 to 350nm.;COPYRIGHT KIPO 2011
