A screen assembly is provided to form a space between plural lens sheets and prevent the damage of lens sheets due to the contact between plural lens sheets. A screen assembly(130) includes plural lens sheets(131,132) so that the images are in parallel arranged on the path for projecting an image. A spacer(133) is equipped between the lens sheets. A supporter(134) fixes the lens sheets. The outside surface of the spacer is positioned at the slightly inside as compared with side surfaces of the lens sheets. The support compresses the lens sheets and spacer and prevents the movement of the plural lens sheets and the spacer.
