Abstract:
Provided is a liquid crystal display device including a liquid crystal cell having a liquid crystal layer between two glass substrates, a front-side polarizing plate provided on a front side of the liquid crystal cell, a rear polarizer provided on a rear side of the liquid crystal cell, and a backlight provided on a rear side of the rear polarizer, in which the front-side polarizing plate has a first protective film, a polarizer, and a second protective film in this order from a surface side opposite to the liquid crystal cell, the first protective film in the front-side polarizing plate is a film including a polyester resin or a polycarbonate resin as a main component, an Re of the first protective film is 3000 nm or higher, an equilibrium moisture content of the second protective film at 25° C. and a relative humidity of 60% is in a range of 1% to 3%, and in the second protective film, a contractile force in a direction orthogonal to an absorption axis of the polarizer is 1.3 times or higher a contractile force in a direction parallel to the absorption axis of the polarizer which is capable of suppressing luminance unevenness at the four corners of the panel when a backlight is turned on after the liquid crystal display device has been stored in a hot and humid environment.
