Patent abstract
A display apparatus capable of preventing wrinkles from occurring on an optical sheet due to thermal expansion, while suppressing damage caused by the movement of the optical sheet when the optical sheet vibrates, is provided. In order to prevent wrinkles from occurring due to thermal expansion while suppressing damage caused by the movement of the optical sheet when the optical sheet vibrates, a clearance between an engaging hole provided in a central engagement flange and the protrusion engaging with the engaging hole is smaller than a clearance between an engaging hole provided in an engagement flange other than the central engagement flange and the protrusion.
