SOLUTION: The optical sheet is constituted by laminating the two or more optical sheets 12, 14, 18 and joining the optical sheets to each other at least at one or more joining points 10A, 10A of their peripheral edges. The joining at the joining points is made releasable. COPYRIGHT: (C)2007,JPO&INPIT
