Abstract: The display apparatus reflects the light emitted from the light source to a display panel using a reflective member without a member such as a light guide plate. The reflective member is configured so that the light emitted from the light source can be provided uniformly and introduced uniformly to the display panel. Even if a board with the light source disposed at a side of the reflective member, the light emitted from the light source can be radiated substantially uniformly to the entire area of the display panel by the reflective surface of the reflective member.

Abstract: A display apparatus includes a plurality of light sources that are arranged in several rows at different intervals so that light emitted from the plurality of light sources may reach all regions of a display panel uniformly. Accordingly, a uniform dispersion of the light incident on the display panel may be achieved. Furthermore, distribution of light generated from the plurality of light sources on the display panel may be facilitated through a reflecting unit without the use of a light-guide plate or the like.

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.
