Abstract
Provided is a liquid crystal display in which occurrence of iridescent unevenness is suppressed, even when a film with high level of mechanical properties, chemical resistance and water-barrier properties is used as a polarizer-protective-film. Also, disclosed is a polarizing plate to be used in the liquid crystal display. The liquid crystal display includes a liquid crystal cell, a light source, a first polarizing plate placed between the liquid crystal cell and the light source, and a second polarizing plate placed on a viewer side of the liquid crystal cell. The first polarizing plate includes a polarizer and a first protective film placed on a light source side principal surface of the first protective film, and the first protective film satisfies following relations: (i) 0 nm≦Re≦3000 nm; (ii) Nz≧5; and (iii) Rth>2500 nm.
