Abstract
An anti-static hard coat film is easy to manufacture, has a high total light transmission, achieves favorable viewability for displayed images, and has a superior balance between an anti-static effect and a resistance to scratch. A hard coat layer made of an ionizing radiation-curable resin and an anti-static layer, which is about 0.03 to 2 μm thick and is made of ionizing radiation-curable resin that includes anti-static particles with an average particle diameter of about 0.01 to 2 μm, are formed in order on a base film, and the Taber abrasion resistance is set at 25 or below as measured in accordance with JIS K5400.
