Abstract
A reflective screen which can reflect high contrast images even in a bright environment and can reflect images with superior image color reproducibility, in particular, images substantially free from color change of the images, even when the screen is observed from an oblique direction. The reflective screenuses a multilayer optical film consisting of at least two kinds of alternately laminated transparent dielectric thin films selectively reflecting lights of specific wavelength regions as a reflecting layer, and the reflecting layerhas a light reflecting property for light in the wavelength regions of blue, green, red, and 670 to 730 nm, and shows average reflectances for lights of the wavelength regions higher than the average reflectance for light in the visible wavelength region other than lights of the wavelength regions, respectively.
