Zusammenfassung:	PCT No. PCT/JP88/00617 Sec. 371 Date Feb. 22, 1990 Sec. 102(e) Date Feb. 22, 1990 PCT Filed Jun. 22, 1988.A transmissive screen for use in a video projector or the like and a manufacturing method thereof is provided wherein a UV-curable resin is coated on a back film or a mold. One surface of a lens surface of opposite shape is formed by the mold. The UV-curable resin is sandwiched between the back film and the mold, ultraviolet rays are irradiated on the UV-curable resin and the screen is released from the mold, thereby forming a transmissive screen in which the lens surface is formed on one surface by the UV-curable resin and the back film is formed on the other surface. Thus, the screen can be reduced in weight and thickness, and can be mass-produced.
