PROBLEM TO BE SOLVED: To provide a reflection screen and picture display system that improve manufacturing efficiency, reduce manufacturing costs, uniform a luminance distribution in a screen plane, and can prevent front surface luminance from falling.SOLUTION: A reflection screen 20 comprises: a lens layer 23 that reflects picture light projected from a picture source LS to display the reflected picture light, includes a lens surface 232 and a non-lens surface 233, and forms a linear Fresnel lens having a unit lens 231 serving as a convex plurally arrayed on an opposite rear face side of a picture source side; a reflection layer 22 that is formed on at least the lens surface 232, and reflects light; and a light control layer 25 that is provided on a picture source side of the lens layer 23, and has a first light transmission unit 252 and second light transmission unit 253 transmitting the light. The first light transmission unit 252 and second light transmission unit 253 extend in an array direction of the unit lens 231, and are alternately arrayed in a direction orthogonal to a thickness direction of the light control layer 25 and the array direction of the unit lens 231.SELECTED DRAWING: Figure 2 |
