Abstract
There is provided a screen, which, with a simple configuration, is capable of effectively utilizing light projected thereon and realizing an even luminance distribution on the screen. This screen has a diffusion layer whose diffusion characteristic expressed as a luminance distribution with respect to a scattering angle of incident light incident at an angle of 0° is varied such that the peak position of the luminance distribution is shifted towards a greater value of scattering angle in the direction of the central portion of the screen the greater the distance from the central portion of the screen is. The present invention also provides an optical film suitable for use in such a screen, and a manufacturing method therefor.
