Abstract
A screen is manufactured by a partial screen manufacturing process, a cutting process, and a bonding process. In the partial screen manufacturing process, partial screens adapted to constitute the screen and each having a plurality of lens elements arranged on a surface are manufactured. In the cutting process, the partial screens are each cut. In the bonding process, the partial screens are bonded to each other on the cutting surfaces of the partial screens thus cut. Thus, since the shape of the molding die for forming the screen can be made smaller, the manufacturing process can be simplified.
