PROBLEM TO BE SOLVED: To provide a roll screen which securely prevents displacement of a screen during winding. SOLUTION: The roll screen R1 comprises a winding shaft 3 which is rotatably held by brackets 2, 2 that are opposedly arranged on both end sides of a frame 1; a screen S to be wound on the winding shaft 3; and a displacement preventing plate 4 for preventing displacement when the screen S fixed on both end sides of the winding shaft 3 is guided and wound. The displacement preventing plate 4 is arranged with its peripheral edge part 41 extended around the periphery of the winding shaft 3. The peripheral edge part 41 of the displacement preventing plate 4 is adjacent to the frame 1, and an interval between the peripheral edge part 41 of the displacement preventing plate 4 and the frame 1 is narrower than the thickness of the screen S.
