Abstract
A backlight assembly and a display device are provided. The backlight assembly includes a light guide plate, a light source, and a first reflector sheet. The light guide plate includes a bottom surface and a light emitting surface opposite to each other, and a light incident surface intersecting the bottom surface and the light emitting surface. The light source is on the light incident surface of the light guide plate. The first reflector sheet is on the bottom surface of the light guide plate and at an end of the light guide plate distal to the light source. The backlight assembly further includes a second reflector sheet proximal to the light source. The second reflector sheet is on the bottom surface and/or the light emitting surface of the light guide plate, and a reflectivity of the second reflector sheet is greater than 90%.
