Anti-glare film, polarizer, liquid-crystal panel, and image display device

An antiglare film, comprising:

• a light transmissive substrate;
• and an antiglare layer that is disposed on the light transmissive substrate and comprises a concavo-convex surface, wherein
• a surface of the antiglare film is a concavo-convex surface;
• the antiglare film has a total haze value of 0% or more and 5% or less;
• the antiglare film has an internal haze value of 0% or more and 5% or less;
• and
• assuming that a transmission image sharpness of the antiglare film, measured using an optical comb with a width of 0.125 mm, is C (0.125), and that a transmission image sharpness of the antiglare film, measured using an optical comb with a width of 0.25 mm, is C (0.25), an expression (1) and an expression (2) described below are satisfied:
• C(0.25)−C(0.125)≧2% (1);
• and
• C(0.125)≧65% (2);
• the antiglare layer comprises therein a binder resin and inorganic oxide fine particles;
• and
• the inorganic oxide fine particles have an average primary particle diameter of 1 nm or more and 100 nm or less.
