Projection screen |
| abstract |
(57) [Summary] [PROBLEMS] To provide a projection screen in which a decrease in screen brightness is small even when the optical axis is changed at a desired angle, and in which unevenness in brightness due to locations in the plane and color unevenness are small. [Structure] From the observer side, a lenticular lens sheet, A projection screen in which a linear Fresnel lens sheet and a circular Fresnel lens sheet are arranged in this order. |
