Abstract:
1. A transverse electric field switch mode type liquid crystal display apparatus, comprising: a liquid crystal cell, and a polarizing plate provided on at least one side of the liquid crystal cell and including two transparent supports A and B and a polarizer sandwiched between the two transparent supports A and B; wherein the transparent support A is a stretched cellulose ester film which contains a polyalcohol ester plasticizer in an amount of 3 to 40% by weight to a total amount of solid content thereof and a phosphoric acid ester plasticizer in an amount less than 1% by weight, and wherein the transparent support B is a stretched cellulose ester film which contains a polymer obtained by polymerization of an ethylenic unsaturated monomer having a weight average molecular weight of from 500 to 30000 and has a retardation value R where nx represents a refractive index in a slow phase axis direction in a film plane, ny represents a refractive index in a fast phase axis direction in the film plane, nz represents the refractive index in a film thickness direction, and d represents a film thickness (nm).
