To obtain a light screen which is low in cost and has a light gain by forming the ring-shaped Fresnel surface of the Fresnel lens into a toric surface.

The Fresnel-shaped surface M formed on the external surface of rises of the toric surface T of the Fresnel lens is formed of Fresnel surfaces 2 (tilt surfaces of a toric curvature surface shape) and rise surfaces 3 (plane rise surface) formed concentrically (circularly) at pitch P on the external surface rising forming the toric surface T, and a circular lens peak surface 4 is formed at the center part of concentric circles. The Fresnel surfaces of the Fresnel lens surface having the ring-shaped Fresnel shape surface composed of the Fresnel surfaces and rise surfaces form the rotationally symmetrical toric surface passing the center of the Fresnel shape surface vertically. Light distribution balance can be kept horizontally and vertically without combining optical components such as a lenticular lens.
