摘要： 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.

摘要： An LED substrate comprises holes having an elliptical shape through which fixing screws are inserted. The fixing screw has a head portion, an unthreaded neck portion whose diameter smaller than that of the head portion, and a threaded shaft portion whose diameter smaller than that of the neck portion. A major axis of the hole is larger than the diameter of the head portion, and a minor axis thereof is smaller than the diameter of the head portion and larger than the diameter of the neck portion. The LED substrate further comprises counterbored recesses to which anchoring claws provided in a cabinet are fitted. A width of the counterbored recess in a direction of the major axis of the hole is larger than that of the anchoring claw. The counterbored recesses are formed on both of two sides of the LED substrate facing each other in a first direction.
