LIQUID CRYSTAL DISPLAY DEVICE

WIPO Patent Application WO/2012/133169

A1

The present invention provides a liquid crystal display device with high front contrast. A liquid crystal display device is provided in which contrast variations and color shifts caused by polarizing plate protective films are not distinguishable and in which no crosstalk is generated in a three-dimensional (3D) image display device when images are observed with one's head inclined. This liquid crystal display device has a viewing side polarizing plate, VA mode liquid crystal cells, and a back light side polarizing plate and is characterized by a polarizing plate protective film positioned on the viewing side of the viewing side polarizing plate being a λ/4 plate and one of the two polarizing plate protective films positioned so as to sandwich the VA mode liquid crystal cells being a film that satisfies prescribed requirements.
