A backlight unit includes a chassis, LED light sources, and a reflection member. The LED light sources are arranged in a matrix on a bottom plate of the chassis. The reflection member includes side wall portions and through holes through which the LED light sources are passed. The side wall portions surround each of the LED light sources passing through the respective through holes. The side wall portions have inclined surfaces on side surfaces thereof that lead light from the LED light sources toward the opening side of the chassis. Each of the side wall portions located between the LED light sources that are adjacently positioned in a diagonal direction has a height greater than a height of each of the side wall portions located between the LED light sources that are adjacently positioned in a vertical direction or in a horizontal direction.
