PROBLEM TO BE SOLVED: To provide a screen capable of achieving high luminance. SOLUTION: A screen 1 has an incident plane 11 on which light forming an image is made incident. The incident plane 11 includes: individual reflection regions reflecting the light; and a plurality of concave portions individually formed along a plurality of rows of substantially circular shapes having reference point A as center point thereof on a plane of either the incident plane 11 or an extended plane of the incident plane 11. A row in the closest proximity to reference point A among the plurality of rows is formed along elliptical orbit having a long side in a direction extending along a virtual reference line B formed by connecting the reference point A to a center point of the incident plane 11.
