Abstract
A liquid crystal display device is provided and includes: a liquid crystal cell including a pair of transparent glass substrates each having a transparent electrode, and a nematic liquid crystal between the pair of the transparent glass substrates; and a pair of polarizing plates sandwiching the liquid crystal cell. At least one of the pair of polarizing plates includes a protective film; a polarizer; and an optical compensation film. One of the pair of transparent glass substrates, an adhesive; the optical compensation film; the polarizer; and the protective film are stacked in this order, and they satisfy the following equations (1) to (3):|1−2|≦0.03  (1)|2−3|≦0.03  (2)|1−3|≦0.03  (3)where n1, n2, and n3 indicate average refractive indices at 589 nm of the one of the pair of the transparent glass electrodes, the adhesive; and the optical compensation film, respectively.
