PURPOSE: A pearlescent high definition projection screen is provided to improve brightness, contrast ratio and resistance to impact, while reducing manufacturing cost and weight. CONSTITUTION: A polymer projection screen base having a multi-layer structure is formed by laminating hard films like a polyester film at both side surfaces of a polymer resin like a polyethylene film. A reflector having a pearl color is formed through a gravure printing method, and a protective film is formed on the reflector. The screen base is formed of polyester films, and has a surface gloss of 20 to 50 percents. |
