Abstract

A display apparatus includes a display panel, a light source part disposed under the display panel configured to supply light to the display panel, and a receiving container. The receiving container is configured to receive the display panel and the light source part. The receiving container includes a bottom portion and a first side wall extending from a first side of the bottom portion along a direction substantially perpendicular to the bottom portion. A first protrusion is formed inside of the first side wall. The first protrusion is disposed between a lower surface of the display panel adjacent to the first side of the display panel and an upper surface of the light source part. The receiving container includes metal.
