摘要： Provided are a backlight unit and a display apparatus including the same. The backlight unit includes a bottom cover, a substrate, light sources, light guide panels, at least one reflective member, and an optical sheet. The substrate is in the bottom cover. The light sources are on the substrate to emit light at an orientation angle from a first direction. The light guide panels include a light incident part having a light incident surface to which light is incident in the first direction from the light sources, and a light emitting part that emits the incident light in a second direction crossing the first direction and has a side connected to the light incident part. The reflective member includes a reflective region overlapping the light guide panel and an extension region that does not overlap the light guide panel. The optical sheet is above the light guide panel.
