Abstract
A backlight unit and a display device including the backlight unit are discussed. By arranging at least one electronic element for driving a light source and the backlight unit on a surface where the light source is disposed in a printed circuit and arranging a pattern having a reflective characteristic in an area where the electronic element is disposed, an image quality of the backlight unit can be maintained and a design structure of the backlight unit can be simplified. In addition, the light source and the electronic element can be disposed on a same surface of the printed circuit so that a space is not present between an opposite surface of the surface of the printed circuit where the light source is disposed and a cover bottom, so the performance of a heat dissipation can be improved in an area where the light source or the electronic element overlaps.
