Provided is a backlight unit capable of reducing luminance unevenness. The backlight unit includes a plurality of dot light sources and a light guide plate in which a predetermined side surface serves as a light incident surface for introducing light from the plurality of dot light sources. The plurality of dot light sources are classified into a first light source group and a second light source group. A mount point of the first light source group and a mount point of the second light source group are displaced from each other in a thickness direction of the light guide plate. A total luminance of the first light source group is higher than a total luminance of the second light source group.
