A hard coat including a nanoparticle mixture and a binder, the nanoparticles constituting from 40 to 95 mass% of an entire mass of the hard coat; from 10 to 50 mass% of the nanoparticles having an average particle size within a range of 2 to 200 nm; from 50 to 90 mass% of the nanoparticles having an average particle size within a range of 60 to 400 nm; a ratio of the average particle size of nanoparticles having an average particle size within the range of 60 to 400 nm to the average particle size of nanoparticles having an average particle size within the range of 2 to 200 nm being within a range of 2:1 to 200:1; and the binder including a polyfunctional fluorinated (meth)acrylic compound, a reaction product thereof, or a combination thereof. The polyfunctional fluorinated (meth)acrylic compound comprises cyclic siloxane units. The particle size distribution of the nanoparticles is bimodal or multimodal.
