PROBLEM TO BE SOLVED: To provide a screen capable of improving luminance of a projection image while suppressing lowering of contrast by influence of external light. SOLUTION: The screen 1 is provided to display the projection image. The screen 1 includes a base material 2 having a reflection surface 21A reflecting incident light, and a projection 3 projecting from the reflection surface 21A. The projection 3 includes a first external surface 4 turning to a lower side, when setting a side of the screen 1 to which the gravity is exerted as a lower side and an opposite side thereto as an upper side, and a second external surface 8 formed at the edge of the projection 3. The first external surface 4 and the second external surface 8 have a light reflecting characteristic to reflect the incident light. COPYRIGHT: (C)2011,JPO&INPIT
