SCREEN

PROBLEM TO BE SOLVED: To provide a screen which improves flatness of a screen base material. SOLUTION: The screen is provided with: a screen base material; a support body 4 that is attached to one face of the screen base material and is substantially orthogonal to a first direction (A direction) which is an extending direction of the screen base material, and is arranged along a second direction (B direction) which is along the one face; and an expansion device 5 that expands and contracts the screen base material. The expansion device 5 is provided with: a supporting member 6 that extends along the second direction and supports an end edge on a tip side of the first direction of the screen base material; and an adjusting mechanism (pantograph linkage) 7 that is configured with a plurality of first rod-shaped members 711, 712, 721 and 722 which are rotatably connected to each other, and extends and contracts along the first direction and adjusts a position of the supporting member 6. The support body 4 is provided with a first guide rail 44 that extends along the second direction, and the adjusting mechanism 7 allows rotation of the first rod-shaped member with respect to the first guide rail 44 and has a first sliding part that slides along the first guide rail 44.
