A lenticular lens medium forms a lenticular lens which comprises a plurality of semicylindrical-shaped or arc-shaped elongated convex parts. The lenticular lens medium has a volume resistivity of 1×107-1×1014&OHgr;·cm and a surface resistivity of 1×108-1×1015&OHgr;/□. The lenticular lens medium including the convex parts has a thickness of 0.3-3 mm.
