摘要： PROBLEM TO BE SOLVED: To provide an optical sheet having both excellent light collecting function and excellent abrasion resistance.
SOLUTION: The optical sheet 40 is provided with: a sheet-like body 45; three or more first unit-shaped elements 50 which are provided on one surface 46 of the body; and a plurality of second unit-shaped elements 55 disposed on the one surface of the body. Each of the second unit-shaped elements extends parallel to one direction on the sheet surface of the body. The height H1 of the first unit-shaped element from the one surface is more than the height H2 of the second unit-shaped element from the one surface. When the optical sheet is observed from the normal line direction (nd) to the one surface, the ratio of a region occupied by the first unit-shaped elements on the one surface is 10.0% or less.
