Abstract
A backlight unit and a display device including the same are disclosed. More specifically, a backlight unit is disclosed that includes a plurality of light sources disposed on a glass substrate and disposed in a plurality of rows and a plurality of columns, and first and second transistors disposed on the glass substrate and spaced apart from each other, wherein each of the first transistor and the second transistor is disposed so as not to overlap the plurality of light sources disposed at points where two rows and two columns cross each other. Thus, image quality is excellent.
