摘要：
In a flat surface illumination device or a liquid crystal display panel, with an aperture disposed in a frame or a case, comprising a circumferential section in which a central section receiving and supporting the light guide and the like is removed, a warp preventing means is formed in such a manner to cross the aperture. The warp preventing means comprises a long and narrow zonal thin plate in which two or more beading processes are performed.
