Abstract: A display device is disclosed. The display device includes: a display panel; an optical layer configured to be positioned behind the display panel; a reflecting sheet configured to be positioned at the rear side of the optical layer; a frame configured to be positioned behind the reflecting sheet; and a supporter configured to be positioned between the optical layer and the reflecting sheet so that the optical layer and the reflecting sheet are spaced apart from each other and to have an elastic portion that at least partially deforms upon deformation of the optical layer. According to the present invention, even if the optical layer deforms, the possibility of damage to the optical layer due to the supporter with the elastic portion can be reduced.

Abstract: Provided is a light-emitting device with reduced in-plane luminance variation. The light-emitting device includes a main substrate, a plurality of light sources, a plurality of lenses, and one or more light reflection members. The main substrate includes a central part and a peripheral part that surrounds the central part. The plurality of light sources are each disposed on the central part of the main substrate. The plurality of lenses are disposed to correspond to the plurality of light sources respectively. The plurality of lenses apply optical effects to beams of light from the plurality of light sources respectively. One or more light reflection members are each disposed on the peripheral part.
