Claims
- 1. An image display having an image display plate comprising a transparent base plate, a film containing ultrafine particles provided thereon, and a binder, said ultrafine particles comprising substantially spherical ultrafine particles, each of which having been treated to have an uneven surface so as to provide the image display plate with an anti-reflection function and high resolution, wherein said substantially spherical ultrafine particles having an uneven surface have an average diameter of not more than 100 nm and have pores formed substantially uniformly on their surface, said pores forming said uneven surface.
- 2. An image display according to claim 1, wherein said substantially spherical ultrafine particles have a porosity of about 50%.
- 3. An image display according to claim 1, wherein a diameter of each of said pores is not more than 50 nm.
- 4. An image display having an image display plate comprising a transparent base plate, a film containing ultrafine particles provided thereon, and a binder, said ultrafine particles comprising substantially spherical ultrafine particles, each of which having been treated to have an uneven surface so as to provide the image display plate with an anti-reflection function and high resolution, wherein each of said substantially spherical ultrafine particles having an uneven surface comprises an aggregate of particles made of the same material, each aggregate having an average particle diameter of not more than 0.2 .mu.m, gaps between the particles forming said uneven surface.
- 5. An image display according to claim 4, wherein said aggregate comprise a plurality of particles having a diameter of not more than 50 nm.
- 6. An image display according to claim 4, wherein said aggregate comprise a plurality of particles having a diameter of not more than 50 nm.
- 7. An image display comprising an image display plate comprising a transparent base plate, a film containing ultrafine particles provided thereon, and a binder, said ultrafine particles comprising substantially spherical ultrafine particles, each of said substantially spherical ultrafine particles having been treated to have an uneven surface so as to provide the image display plate with an anti-reflection function and high resolution, wherein each of said substantially spherical ultrafine particles comprises an aggregate of particles, wherein each aggregate comprises a first particle having an average particle diameter of 100 to 150 nm and a plurality of second, smaller particles adsorbed on a surface thereof, wherein said second, smaller particles are electrically conductive.
- 8. An image display according to claim 7, wherein said second smaller particles are made of a material selected from the group consisting of SnO.sub.2, Sb.sub.2 O.sub.3 and In.sub.2 O.sub.3.
- 9. An image display according to claim 8, wherein said second, smaller particles have an average particle diameter not more than 1/10 of the average particle diameter of said first particle.
- 10. An image display according to claim 9, wherein said first particle is made of at least one material selected from the group consisting of SiO.sub.2 and MgF.sub.2.
