Abstract:
The present invention aims to provide a liquid crystal display device highly suppressing occurrence of rainbow interference pattern in displayed images. The present invention is a liquid crystal display device including: a back light source, a liquid crystal cell, a color filter, a polarizer, and a polarizer protective film arranged in the stated order, wherein the polarizer protective film has a retardation of not less than 6000 nm, and a difference (nx−ny) of not less than 0.05 between a refractive index (nx) in a slow axis direction that is a highest refractive index direction and a refractive index (ny) in a fast axis direction that is orthogonal to the slow axis direction, and an absorption axis of the polarizer and the slow axis of the polarizer protective film are arranged to form an angle within a range of 0°±30° or 90°±30°.

Claim (Index 2):
The display device according to  claim 1 , comprising a plurality of polarizers, and wherein the polarizer protective film is arranged between a polarizer of the plurality of the polarizers closest to the view side of the device and the top surface of the view side of the device.
