Zusammenfassung:	Provided is a display apparatus (101) comprising a liquid crystal panel (122) and a light-emitting device (1). The light-emitting device (1) comprises a main substrate (40) that includes a central part and a peripheral part that surrounds the central part, a plurality of light sources (10) that are disposed on the central part of the main substrate (40). The light-emitting device (1) comprises a plurality of lenses disposed on the plurality of light sources (10) to cover the tops and sides of the light sources, the plurality of lenses applying optical effects to beams of light from the plurality of light sources (10) respectively. The light-emitting device (1) comprises one or more light reflection members (50) that are disposed on the peripheral part, the light reflection members (50) having reflectance that is higher than the reflectance of the main substrate (40). The light-emitting device (1) comprises a reflection sheet (70) that covers the main substrate (40), The one or more light reflection members (50) are in the corners of the peripheral part and provide a higher light reflectance in the corners than other portions of the peripheral part.
