PROJECTED FILM FORMING METHOD

摘要

A projected film forming method capable of lowering a production cost by establishing a projected part control method capable of using a coating liquid common to a plurality of requested scattering characteristics to suppress an increase in the number of mixings and the replacement frequency of the coating liquid so as to prevent the operation rate of coating equipment from being lowered, comprising a forming step for forming a coated layer 41 by coating sol-like coating liquid formed of at least one type of film component and at least two types of solvents on a glass substrate 20, a phase-separating step for phase-separating by drying the solvents effectively acting for homogenization on the coated layer 41 while selectively removing and by utilizing a difference in surface tension between the solvent effectively acting for phase separation and the film component or between the film components, and a gelation step for gelating the film component, wherein a drying temperature for the coated layer 41 is controlled to 200 to 500 ° C, and a drying time is controlled to 1 min. to 24 hours.
