摘要： PROBLEM TO BE SOLVED: To provide an optical sheet allowing a luminance peak of light made incident obliquely to a normal to be brought close to the normal direction and widening a visual field angle.
SOLUTION: The optical sheet includes a rear surface receiving a peak light ray R15 inclined in a +X direction to the normal N5 and an irregular surface having a plurality of columnar lens parts 60 formed thereon. The cross sectional shape of the columnar lens part 60 is a mountain shape, and has a main inclined plane 61 and a sub inclined plane 62 facing the opposite directions. The sub inclined plane includes a refractive plane 621 and a reflective plane 622. An incident normal NI61 of the main inclined plane 61 is inclined on the same side as the peak light ray R15 to the normal N5, and an incident normal NI621 of the refractive plane 621 is inclined on the side opposite to the peak light ray R15 to the normal N5. An area AR61 of the main inclined plane 61 is larger than an area AR621 of the refractive plane 621 when the columnar lens part 60 is viewed from directly above.
