Process for forming ultrafine particle film, transparent plate and image display plate

A process for forming films on a surface of a substrate, comprising the steps of:

• introducing a first coating solution containing antistatic ultrafine particles having an average particle size of 10 nm or less and a binder into a container in which is provided at least the surface of the substrate until said surface is covered with said first coating solution;
• subsequently discharging said first coating solution from said container to coat said surface with said first coating solution, thereby forming a first film containing antistatic ultrafine particles on said surface;
• subsequently introducing a second coating solution containing anti-reflection ultrafine particles having an average particle size of 80 to 150 nm and a binder into said container until said surface having said first film provided thereon is covered with said second coating solution;
• and
• subsequently discharging said second coating solution from said container to coat said surface having said first film provided thereon with said second coating solution, thereby forming a second film containing anti-reflection ultrafine particles on said first film,
• wherein the second coating solution is discharged at a rate sufficient to provide said second film in which said anti-reflection ultrafine particles are regularly arranged in a single layer in such a manner that any area not having said anti-reflection ultrafine particles present has a length less than visible light wavelength.
