Cellulose acylate film, polarizing plate using the same and liquid crystal display device

Abstract

A cellulose acylate film containing cellulose acylate and a polymer, the polymer containing a repeating unit derived from a monomer represented by formula (1); a polarizing plate containing a polarizing element and two protective films disposed on both sides of the polarizing element, at least one of the two protective films being made of the cellulose acylate film described above; and a liquid crystal display device containing a liquid crystal cell and two polarizing plates disposed on both sides of the liquid crystal cell, at least one of the polarizing plates being made of the polarizing plate described above: wherein R1 represents a hydrogen atom or an aliphatic group having 1 to 4 carbon atoms, and R2 represents an aliphatic group or an aromatic group.
