Abstract
A display board has a substrate, a transparent photopolymerization resin layer formed on the substrate, and a picture layer formed in a surface of the transparent photopolymerization resin layer. The picture layer is composed of at least one dots-shaped colored photopolymerization resin. This display board is produced by exposing a colored photopolymerization resin film supported by a support member through a negative having a predetermined picture pattern to form a dots-shaped colored photopolymerization resin layer on the support member, transferring the dots-shaped colored photopolymerization resin layer to a surface of a transparent photopolymerization resin layer formed on a substrate to form a picture layer in the surface of the transparent photopolymerization resin layer, and setting the transparent photopolymerization resin layer in which the picture layer is formed to fix the picture layer.
