Polarizing plate and liquid crystal display apparatus using the same |
摘要 |
A polarizing plate includes two transparent supports A and B; and a polarizer sandwiched between the two transparent supports A and B; wherein (i) the transparent support A is a stretched cellulose ester film (a) which contains a non-phosphoric acid ester plasticizer and substantially does not contain a phosphoric acid ester plasticizer, and wherein (ii) the transparent support B is a stretched cellulose ester film (b) which has a retardation value R0 of from 0 nm to 10 nm and a retardation value Rt of from −30 nm to 20 nm, and the retardation value R0 and the retardation value Rt are defined by the following formulas (I) and (II): Ro=(nx−ny)×d  Formula (I): Rt={(nx+ny)/2−nz}×d.  Formula (II):
