Abstract:
Provided is a liquid crystal display device that has excellent visibility while using a protective film comprising a polyester film. The liquid crystal display device comprises a backlight light source, and a liquid crystal cell disposed between two polarizers; the backlight light source being a white light-emitting diode; each of the polarizers comprising a polarizing film and protective films laminated on both sides of the polarizing film; and at least one of the protective films being a polyester film having a retardation of 3,000 to 30,000 nm.

Claim (Index 1):
A display device comprising a first polarizer, a second polarizer, a liquid crystal cell, and a backlight source, wherein\n the liquid crystal cell has a light-outgoing side and a light-incoming side, the first polarizer is disposed on the light-outgoing side of the liquid crystal cell, the first polarizer comprises (a) a first polarizing film and (b) a first protective film laminated on the light-outgoing side of the first polarizing film, the second polarizer is disposed on the light-incoming side of the liquid crystal cell, the second polarizer comprises (a) a second polarizing film and (b) a second protective film laminated on the light-incoming side of the second polarizing film, at least one of the first protective film and the second protective film is an oriented film having an in-plane retardation of 3,215 to 30,000 nm and a ratio of in-plane retardation to thickness-direction retardation (Re/Rth) of 0.2 to 2.0, and no oriented film having an in-plane retardation of 3,215 to 30,000 nm is disposed between the light-incoming side of the first polarizing film and the light-outgoing side of the second polarizing film.
