Abstract: Provided is a liquid crystal display device in which the scattering of a light control film becomes uniform on a pixel by pixel basis. A liquid crystal display device 1 includes: a light source 2; a liquid crystal panel 4 that modulates light emitted from the light source 2; and a light control film 7 that uses a total reflection and is disposed closer to a viewer side than to the liquid crystal panel 4. The light control film 7 includes a base substrate 39 having light transmission property, and a light-shielding layer 40 and a light diffusing portion 41 formed on one surface side of the base substrate 39. Patterns of the light-shielding layer 40 are anisotropic. A longitudinal direction of the patterns and a longitudinal direction of one region in which a property of the liquid crystal panel 4 is approximately equal intersect each other.
