The liquid crystal display device, a polarizing plate and a polarizer protective film

To provide a liquid crystal display device in which generation of rainbow unevenness is suppressed in the case of using the oriented polyester film as a polarizer protective film of both of the pair of polarizing plates. Backlight, a liquid crystal display device having two polarizers and liquid crystal cells arranged in said two polarizing plates, the backlight light source is a white light source having an emission spectrum which is continuous, the polarizing plate a obtained by laminating a polarizer protective film on both sides of the polarizer configuration, the at least one, and polarizer protective film of the polarizing plate disposed on the exit light side of the polarizer protective film of the polarizing plate arranged on the incident light side at least one of a oriented polyester film having retardation and 1.7 below Nz coefficient of 4000～30000Nm, a liquid crystal display device.
