This liquid composition for forming a low-refractive film is prepared by: combining a hydrolysate of a silicon alkoxide with a silica sol, said hydrolysate being generated by adding a mixture of water and nitric acid to an alcohol solution of tetramethoxysilane or tetraethoxysilane serving as a silicon alkoxide and stirring the resulting product, and said silica sol being obtained by dispersing beaded colloidal silica particles in a liquid medium; and further combining with an organic solvent of a glycol ether. Said glycol ether is a solvent having a flash point between 140-160 DEG C inclusive.
