<P>PROBLEM TO BE SOLVED: To provide a light diffusing member for a transmittance screen having sufficient surface protection effect while maintaining excellent light diffusing effect and reflection prevention effect. <P>SOLUTION: In the light diffusing member for a transmittance screen providing a hard coat layer on a base substance surface comprising at least one or more layer, particulates are contained in a base substance and the hard coat layer, and the average particulate diameter of the particulates contained in the hard coat layer is 5-15 μm. When the average particulate diameter of the particulates is d (μm); a film thickness t (μm) of the hard coat layer is in a range of (d-2)≤t≤d, and a part of the particulates is projected on the surface of the hard coat layer to form irregularity. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
