PROBLEM TO BE SOLVED: To provide a screen that can be reduced in length and width when not in use and can easily be returned to its original shape when in use, and has extremely high portability. SOLUTION: To use the screen 10, the screen 10 is unfolded and spread. The unfolded screen 10 can be hanged on a wall or the like by the use of attaching devices 20 as shown in Figure. In this case, folding line 10a formed when the screen 10 is folded potentially remains. Such folding line 10a is seen as a distorted image and undesirable, then, heat is applied to the folding line or the like in the screen 10 with a dryer or the like. As a result, linear bodies 11d embedded in the main body base material 11 of the screen 10 in the form of a grid are heated and the screen returns to its original shape. Thus, the screen 10 is made flat as a whole including the folding line 10a. By projecting an image onto such a screen 10, beautiful images free from partial distortion are formed on the entire surface of the screen. COPYRIGHT: (C)2006,JPO&NCIPI
