Abstract
A backlight device includes a substrate and a plurality of light emitters on the substrate. Each of the plurality of light emitters includes a brightness controller disposed on the substrate, and a pad unit disposed on the substrate. The brightness controller generates a light-emission current, a light-emitting diode is allowed to be disposed on the pad unit, and the light-emitting diode emits light based on the light-emission current.
