an optical substrate;
a hard coat layer provided directly, or over another layer(s), on the optical substrate;
an antireflective layer provided on the hard coat layer; and
an antifouling layer provided on the antireflective layer;
such that when a friction and wear test is conducted on the surface of the antifouling layer under conditions of a scratching rate of 0.1 mm/s and a load increase rate of 0.15 gf/s with a diamond stylus having a tip diameter of 0.03 mm, the load at which the antireflective layer begins to peel off is greater than 50 gf. |
