Patent abstract
The screen of the invention comprises an oriented film having a direction of maximum scattering (scattering axis) and a direction of minimum scattering (transmitting axis) for linear polarized light, and containing macromolecular fine particles in a macromolecular matrix, wherein the refractive index of the macromolecular fine particles is within a specified range and the matrix and macromolecular fine particles satisfy a specified relationship. The screen reproduces bright and high-quality projected images with virtually no moire effect or glare, and is therefore highly useful as a transmissive or reflective projector screen.
