发明名称 POLARIZING PLATE
摘要 <P>PROBLEM TO BE SOLVED: To provide a polarizing plate which provides satisfactory strength, punching properties and flexibility, does not have change in the size in high-temperature and high-humidity environment, has high optical performance and can be used suitably for a liquid crystal display, a touch panel or the like. <P>SOLUTION: The polarizing plate is provided with a polarizer, a protection film disposed on one side surface of the polarizer, and an optical anisotropic body disposed on the other side surface of the polarizer. The protective film is provided with a plurality of layers made of thermoplastic resin, with a total thickness of 200 &mu;m or smaller and moisture permeability of 10 to 200 g/mm<SP>2</SP>24 hr. In the optical anisotropic body, the ratio Re(450)/Re(550) for retardation Re(550), measured at a wavelength range of 550 nm to retardation Re(450) measured at wavelength 450 nm, is 1.007 or smaller. <P>COPYRIGHT: (C)2007,JPO&INPIT
