Abstract: According to one embodiment, a liquid crystal display device includes a first substrate, a second substrate disposed to oppose the first substrate, a layer of liquid crystal located between the first substrate and the second substrate, and an alignment film disposed on the first substrate so as to be in contact with the layer of the liquid crystal. The liquid crystal has a refractive-index anisotropy Δn of 0.11 or more, the layer of the liquid crystal has a thickness d of 2.5 μm or less, and a product Δnd of the refractive-index anisotropy Δn and the thickness d is 0.20 or more but 0.31 or less. The transmissivity of light having a wavelength of 450 nm in the first substrate and the alignment film is 85% or more but 97% or less.
