摘要: A longitudinal-stripe lenticular lens screen and a transverse-stripe lenticular lens screen are superposed, and a light diffusing agent is mixed only in the longitudinal-stripe lenticular lens screen. Therefore, the light transmittance is high although the angle of view can be three-dimensionally widened by the two lenticular lens screens. In addition, since scan lines of an image are blurred by two diffusion planes, Moire becomes inconspicuous.
