A liquid crystal display device includes first and second polarizers with absorption axes orthogonal to each other; first and second substrates between the first and second polarizers and at least one of which has a transparent electrode; and a twisted-nematic liquid crystal cell disposed between the first and second substrates, wherein a light scattering film is provided at a viewing side of the first and second polarizers and includes a support member and a liquid crystal layer composed of a liquid crystal compound, wherein the pitch of the liquid crystal compound ranges between 0.35 μm and 3 μm and is oriented at 45° relative to a liquid-crystal direction of the liquid crystal display device, wherein the liquid crystal layer has a thickness between 0.17 μm and 10 μm, and wherein a weighted scattering area ratio of a goniophotometer scattering profile of the light scattering film satisfies the following expression. S 60 / ( S 0 ) 2 × 1000 > 40 S 0 = ∑ S 0 ⁡ ( θ ) × θ ∑ S 0 ⁡ ( θ ) S 60 = ∑ S 60 ⁡ ( θ ) × exp ⁡ ( - 0.2 × θ ) ∑ S 60 ⁡ ( θ )
