Abstract
A liquid crystal display apparatus, includes: a light-condensing backlight unit; a liquid crystal panel including a first linear polarizer and a second linear polarizer; a light scattering film facing the second linear polarizer; and a third linear polarizer facing the light scattering film. The light scattering film includes a functional layer including an organic polymer compound and light scattering particles. The functional layer includes a particle layer in which a fraction of 60% by volume to 100% by volume of the light scattering particles included in the functional layer expands along a surface of the particle layer at which the light output from the liquid crystal panel is received, and the particle layer is concentrated to a region having a thickness of 1 to 80% of a total thickness of the functional layer, in a direction perpendicular to the contact surface.
