Abstract
Embodiments of the present disclosure relate to a printed circuit, a backlight unit, and a display device. The printed circuit on which a light source is mounted can be easily manufactured in a single form, by depositing and arranging a wiring layer on a substrate and mounting the light source on the wiring layer. Further, the printed circuit is arranged so that the wiring layer includes a plurality of bonding metal layers and a plurality of wiring metal layers, and a part of the bonding metal layer positioned between the plurality of wiring metal layers and disposed in an area overlapping a pad portion of the light source is removed. Therefore, even though the main metal layer of the wiring layer is removed during reworking, it is possible to provide the printed circuit capable of electrically connecting to the light source by the sub-metal layer of the wiring layer.
