Patent ID: 8159634

Claim:
A liquid crystal display device comprising: a backlight; a liquid crystal cell; a first polarizing plate provided between the liquid crystal cell and the backlight; a second polarizing plate provided in opposite side to the first polarizing plate with respect to the liquid crystal cell; a first retardation film provided between the first polarizing plate and the liquid crystal cell; and a second retardation film provided between the second polarizing plate and the liquid crystal cell, wherein a relationship represented by the following formula (1) is satisfied: 1×10 −6 /° C.≦ EC 2max− EC 1max≦50×10 −6 /° C. (1) in which EC1max represents a maximal linear thermal expansion coefficient of the first retardation film, and EC2max represents a maximal linear thermal expansion coefficient of the second retardation film.
