ABSTRACT:
There is provided a surface protective member for a transmission screen that has excellent antireflective effect while maintaining a surface protective effect. The surface protective member for a transmission screen comprises a fine particle-containing hard coat layer provided on a transparent substrate, wherein the average particle diameter of the fine particles is 5 to 15 μm, the hard coat layer has a thickness satisfying a requirement represented by formula (d−2)≦t≦d wherein t represents the thickness of the hard coat layer, μm; and d represents the average particle diameter of the fine particles, μm, and a part of the fine particles is projected on the surface of the hard coat layer to constitute concaves and convexes.
