Title:
COMPOSITE POLARIZING PLATE WITH WIDE FIELD OF VIEW AND LIQUID CRYSTAL DISPLAY
Document Type and Number:
WIPO Patent Application WO/2007/097407
Kind Code:
A1
Abstract:
A composite polarizing plate with a wide field of view, in which a linear polarizing plate is laminated on an optical compensation film where an optical anisotropy layer having a positive uniaxiality and an optical axis in the direction normal to the film is formed on one surface of a transparent base exhibiting a phase difference in the surface of the film, when the optical anisotropy layer side of the optical compensation film is used as a joining surface, the slow axis of the transparent base forming the optical compensation film and the absorption axis of the linear polarizing plate are generally parallel with each other, and when the transparent base side of the optical compensation film is used as the joining surface, the slow axis of the transparent base and the absorption axis of the linear polarizing plate are generally perpendicular to each other.
