摘要：
The method for producing an optical film includes a step of preparing a first coating liquid containing a certain amount of light-transmitting particles, a resin, and a solvent, a second coating liquid containing an amount less than the certain amount of light-transmitting particles, a resin, and a solvent, or not containing the light-transmitting particles but containing a resin and a solvent; a step of coating the second coating liquid and the first coating liquid in this order from the support side on a traveling band-shaped support in the form of a multilayer to form a second coating film and a first coating film; a step of transferring the light-transmitting particles in the first coating film to the side of the second coating film while drying the first coating film and the second coating film.
