Abstract: A backlight unit having a supplementary lamp for a smooth starting operation includes multiple light-emitting lamps arranged in one direction on a cover bottom; an inverter printed circuit board (PCB) provided at one rear side or both rear sides of the cover bottom; a first hole provided at a predetermined portion of the inverter PCB; a supplementary lamp provided in the first hole of the inverter PCB; and a second hole provided at a predetermined portion of the cover bottom corresponding to the supplementary lamp.

Abstract: A display device includes a display panel; a plurality of lamps facing the display panel and arranged in parallel; and at least one transformer connected to the plurality of lamps, wherein the at least one transformer is disposed at a lower portion of the display device adjacent to a ground. A transformer may include a driving transformer and a compensation transformer, where the compensation transformer may be connected to one or more lower lamps and the driving transformer may be connected to the remainder of the lamps. The output voltages of the compensation transformer and the driving transformer may differ.
