Abstract:
1. A method for producing an antiglare film which comprises, a step of preparing at least one antiglare layer-forming coating lquid in which at least two resin materials incompatible with each other are dissolved in at least one solvent, and a low-refractive index layer-forming coating liquid in which a resin material and hydrophobic particles are dissolved in a solvent; a coating step of applying the low-refractive index layer-forming coating liquid as an upper layer and the antiglare layer-forming coating liquid as a lower layer on a support to form a coating layer; a particle movement step of moving the particles to a gas-liquid interface of the coating layer; and a drying step of drying the coating layer and making the coating layer cause phase-separation so as to form an antiglare layer and a low-refractive index layer wherein, when a mass ratio of the particles to the solvent in the low-refractive index layer-forming coating liquid is represented by r [-], a time until the solvent decreases to half in the drying step is represented by t [s], and an initial film thickness of the upper layer in the coating, step is represented by d [m], the factors, r, t and d, are adjusted so that multiplication of 1/r and t and d satisfies 6×10
