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.

Claim (Index 1):
A display apparatus comprising:\n a display panel including a front surface on which an image is displayed and a rear surface opposite to the front surface; an optical sheet having a rectangular shape, the optical sheet having a front surface facing the rear surface of the display panel and a rear surface opposite to the front surface of the optical sheet; and a holding member being a frame body having a rectangular opening, the holding member having a front surface facing the rear surface of the optical sheet and a rear surface opposite to the front surface of the holding member wherein the optical sheet has a plurality of engaging holes formed in a peripheral region of the optical sheet along one side of the optical sheet, the holding member has a plurality of protrusions provided on the front surface of the holding member and each of the plurality of protrusions is engaged with one engaging hole of the plurality of engaging holes to hold the optical sheet so that the front surface of the optical sheet faces the rear surface of the display panel, the plurality of engaging holes include a first engaging hole provided to a central region of the one side of the optical sheet and at least one second engaging hole provided to a region other than the central region, the plurality of protrusions include a first protrusion engaged with the first engaging hole and at least one second protrusion engaged with the at least one second engaging hole, a distance in a first direction along the one side of the optical sheet between an edge of the first engaging hole and the first protrusion is shorter than a distance in the first direction between an edge of the at least one second engaging hole and the at least one second protrusion, and the distance in the first direction between the edge of the first engaging hole and the first protrusion is shorter than a distance in a second direction orthogonal to the first direction between the edge of the first engaging hole and the first protrusion.
