Abstract: A display apparatus includes plural light source units each including a light emitting device and a lens portion; a reflection sheet defining plural holes thereof and into which the light source units are respectively disposed; and a display panel on the reflection sheet. The lens portion defines: a body portion; and plural side protruding portions and respectively at opposing sides of the body portion in a first direction in a top plan view. The hole of the reflection sheet is defined by: an edge of a first hole; an edge of a second hole facing the first hole in a second direction crossing the first direction, the second hole larger than the first hole; and slanted edges connecting the first hole to the second hole. In a fixed state of the reflection sheet, a predetermined area of the reflection sheet adjacent to the slanted edges overlaps the side protruding portions.
