Provided is a display apparatus having a structure of fixing an optical sheet to allow the optical sheet to expand uniformly even when a display is rotated. The display apparatus includes a liquid crystal panel; a backlight unit arranged to supply light to the liquid crystal panel; an optical sheet provided between the liquid crystal panel and the backlight unit and having a hole formed therein; and a sheet fixer configured to fix the optical sheet, wherein the sheet fixer includes: an anti-deviation projection inserted in the hole of the optical sheet to restrict movement of the optical sheet in a first direction, and a supporting projection contacting the optical sheet to restrict movement of the optical sheet in a second direction opposite the first direction.
