SCREEN FOR PROJECTION AND WHITEBOARD DEVICE USING THE SAME

PROBLEM TO BE SOLVED: To provide a screen for projection which has little wear on a projection/writing surface even though writing and erasing by a whiteboard marker is repeated, in which diffusion reflectivity of projection light is retained and which suppresses occurrence of hot spots, and to provide a whiteboard device using the same.SOLUTION: As a configuration of a projection/writing surface, in forming the projection surface having fine surface unevenness by a base material and a coating layer which is formed on the base material surface and which contains a plurality of fine particles, ultra-high molecular weight polyolefin fine particles are used as fine particles. As the wear resistance of the surface unevenness of the projection/writing surface greatly improves, even though writing and erasing by a whiteboard marker is repeated, the projection/writing surface has little wear, diffusion reflectivity of projection light is retained, and the occurrence of hot spots can be suppressed.
