Zusammenfassung:A backlight unit (100) for a display apparatus (1) includes a bottom cover (110), a substrate (14), light sources (13), light guide panels (15), at least one reflective member (17), and an optical sheet (220). The light sources (13) are on the substrate (14) and the substrate (14) is in the bottom cover. The light guide panels (15) include: a light incident part (15b) having a light incident surface (151) to which light from the light sources is incident in a first direction; and a light emitting part (15a) emits the incident light, in a second direction crossing the first direction, optical sheet is above the light guide panel. A side of the light emitting part (15a) is connected to the light incident part (15b). The reflective member (17) includes a reflective region (171) overlapping the light guide panel (15) and an extension region (172) that does not overlap the light guide panel (15).
