Abstract
The present invention is a liquid crystal display device including a first polarizer, a first protective layer, a first substrate, a first optical alignment film, a liquid crystal layer, a second optical alignment film, a second substrate including a signal electrode and an opposite electrode, a second protective layer, a second polarizer in this order, in which the layers satisfy the relationship nx=ny≥nz, an in-plane retardation of each of optical alignment films is greater than or equal to 1 nm, given that Ris a thickness-direction retardation of each of the protective layers and that Ris the in-plane retardation of each of optical alignment films, the relationship R≤0.047R−2.1R+44.3 is satisfied, the liquid crystal layer has a positive dielectric anisotropy, and a transmission axis of the second polarizer is perpendicular to an initial alignment direction of the liquid crystal molecules.
