An optical sheet for display use wherein two or more optical sheets are stacked therein and the optical sheets are joined to one another on one peripheral side of each by a thermoadhesive film is to be provided. Also an optical sheet for display use wherein two or more optical sheets are stacked therein and the optical sheets are joined to one another on two or more peripheral sides of each by a thermoadhesive film is to be provided. Since the optical sheets are joined to one another on one peripheral side or two or more peripheral sides of each by a thermoadhesive film, the step of cutting each of multiple films (sheets) into the product size can be omitted, and so can be the step of stacking multiple layers of films (sheets) while positioning them. Also, it is free from a problem which derives from protective sheets, resulting in advantages in both cost and quality aspects. Moreover, it is free from a problem which arises when multiple layers of films are stacked.
