Abstract: A backlight module includes first and second light guide plates, an anti-peeping film, and first and second light sources. The anti-peeping film is located on a first light exit surface of the first light guide plates. The second light guide plate is located on a side of the anti-peeping film away from the first light guide plate. The first light source is opposite a first light incident surface of the first light guide plate. The second light source includes a first portion extending along the direction perpendicular to the reference plane and opposite a second light incident surface of the second light guide plate. A side of the first light source proximate to the fist light guide plate is staggered from a side of the second light source proximate to the second light guide plate, and closer to center of the first light guide plate than the second light source.
