PROBLEM TO BE SOLVED: To provide an optical film having an antidazzle face which develops sufficient ability to prevent reflection and does not produce a pale color state of the screen. SOLUTION: The optical film has minute recesses and projections formed on the surface. When rays are made incident to the film surface in the direction of -10 deg. angle with respect to the normal line to observe only the reflected light from the surface, the profile of the reflected light observed in the plane including the normal line of the film and the incident direction satisfies the following relation. The relation is expressed by (I): WH>=7 deg. and (II): I(30 deg.)/I(10 deg.)<=0.2, wherein WH is the half width of the peak in the profile of the reflected light and I(θ deg.) is the intensity of the reflected light observed in the direction of the angle θ deg.. |
