PROBLEM TO BE SOLVED: To provide a hard coating film which has high hardness and is excellent in flexibility, weather resistance, transparency, wear resistance, anti-glare property and anti-fouling property. SOLUTION: The hard coating film used for solving the problem is the one prepared using an anti-glare hard coating liquid comprising organic-inorganic silica particles, a polyfunctional (meth)acrylate, an initiator and silicon particulates, wherein the organic-inorganic silica particles are prepared by chemically bonding a polyfunctional silane compound containing polyfunctional (meth)acrylate to a hydroxy group on the surface of the silica particles.
