This abstract first appeared for US patent application 20240411077 titled 'POLARIZING PLATE AND OPTICAL DISPLAY DEVICE
Original Abstract Submitted
a polarizing plate and an optical display device are disclosed. a polarizing plate includes a polarizer, and a retardation layer laminated on a surface of the polarizer, the retardation layer includes a retardation film that satisfies a relationship of nx>nz>ny, where nx, ny, and nz are indexes of refraction of the retardation film in a slow axis direction, a fast axis direction, and a thickness direction of the retardation film, respectively, at a wavelength of 550 nm, an alignment direction of a main chain of a resin contained in the retardation film with respect to a light transmission axis of the polarizer is in a range from −5� to +5�, and the retardation film has a degree of biaxiality of 0.2 to 0.6 at the wavelength of 550 nm.
