Abstract
Official abstract text for this publication.
A backlight unit has a Light Emitting Diode (LED). The backlight unit includes a base member, and a light source unit provided on the base member and including p light source blocks, where p is a natural number equal to or greater than 2. The light source blocks are sequentially arranged to emit light, and each of the light source blocks includes at least one LED package. The LED package includes an LED configured to generate light in response to a driving voltage applied from the outside. A main lead is connected to the LED and configured to apply the driving voltage to the LED. At least one sub lead is separated from the main lead and configured to provide the driving voltage to an adjacent light source block.
