Abstract
A display apparatus includes a display panel which receives light to display an image. A light guide plate guides the light toward the display panel. A light source unit is disposed at a first side of the light guide plate to provide the light to the light guide plate. The light source unit includes a printed circuit board which includes a first area and a second area. A first light source is disposed on the first area and generates the light. A first stepped part is disposed on the second area and faces the first light source. A first adhesive part is disposed on the second area. The first stepped part reflects the light which is generated from the first light source toward the light guide plate, and the first adhesive part attaches the printed circuit board to the light guide plate.
