Abstract

Abstract PURPOSE:To obtain a bright screen and to watch an image very clearly in a bright room by arranging transparent beads which can converge light all over the surface of a light reflection layer and using silver ink as the reflection layer. CONSTITUTION:The light is transmitted through the transparent bead which can converge the light, but the light which ought to be transmitted to the back surface of the bead 4 is reflected by the reflection layer 2 into the bead and exits toward an incident surface again because the reflection layer 2 is provided on the back surfaced of the bead 4. Therefore, the back surface of the bead 4 becomes the reflection surface. For example, the bead 4 having 100mum diameter is used and the silver ink for screen printing is used as the reflection layer 2, then the silver ink is thickly painted and dried on the foundation cloth of the back surface. By using the silver material which is excellent in reflection characteristic as the reflection layer 2, the bright image is offered even in the case of the image projected on a screen from a projection type television projector which is somewhat short of the light quantity of a light source.
