Abstract

A display apparatus that includes a display panel, a plurality of light sources disposed in upper and lower side directions and in left and right side directions at a rear side of the display panel while spaced apart from one another, a reflective sheet to reflect light generated from the plurality of light sources to the display panel, and a middle holder to support a periphery of the reflective sheet, wherein the middle holder includes a plurality of concave parts each provided at a position corresponding to each of the light sources that is positioned at an outer side among the plurality of the light sources. Most of the light incident from the light sources positioned at the outer side toward the middle holder is reflected while diffused by an inner surface of the concave part, and thus occurrence of a light portion and a dark portion at a periphery of a display panel can be reduced.
