    Abstract: Disclosed is a display device. The display device according to an aspect of the present disclosure may include: a display panel; a frame which is positioned behind the display panel, and to which the display panel is coupled; a plurality of substrates which are positioned between the display panel and the frame, on which a plurality of light sources providing light to the display panel are mounted, and which are formed of flat plates separated from each other; and a reflective sheet positioned between the display panel and the plurality of substrates, covering the plurality of substrates, and having a plurality of holes corresponding to the plurality of light sources, wherein the plurality of substrates may include: a first substrate; a second substrate next to the first substrate; and a third substrate next to the second substrate, wherein the reflective sheet may include: a first reflective sheet covering at least a portion of the first substrate and a portion of the second substrate; and a second reflective sheet covering another portion of the second substrate and at least a portion of the third substrate.
