リーン。In a transmission screen formed by orthogonally disposing two lenticular lens plates each having a lenticular lens provided on both surfaces of a light-transmitting substrate so that their optical axes substantially coincide with each other,
Each of the above-mentioned lenticular lens plates is made up of a plurality of lenticular lens plate constituent pieces each having a lenticular lens provided thereon so that their optical axes substantially coincide with both surfaces of a light-transmissive substrate, and are bonded together at their side ends; Among the joint parts of each lenticular lens plate mentioned above, at the joint part in the center of each lenticular lens plate, the joint position of the lenticular tongue plate is between the most concave parts of the lenticular lens, and goes to the end of the lenticular lens plate. Accordingly, there is provided a transmission screen characterized in that the bonding positions of the bonding portions are sequentially shifted from the most concave portions of the lenticular lenses toward the ends thereof.
