摘要： An optical film has a transparent film including light output portions distributed over one of opposite surfaces of the transparent film so as to make the total luminous transmittance and the haze of the optical film be set in a range of from 75 to 92% and in a range of from 4 to 20% respectively, the light output portions being constituted by concave or convex portions having optical path changing slopes each inclined at an inclination angle of from 35 to 48 degrees with respect to a film plane of the transparent film. A liquid-crystal display device has an optical film defined above, and a liquid-crystal display panel, wherein the optical film is disposed on one of opposite surfaces of the liquid-crystal display panel so that a surface of the film in which the light output portions of the optical film are provided faces outward.
