Abstract
According to embodiments of the disclosure, it is possible to increase scattering effect and light reflectance in the area around the light source by increasing the ratio of the base layer exposed around the light source, which have protrusion patterns and have a higher reflectance than the cover layer and are positioned under the cover layer and the wiring layer of the printed circuit where the light source included in the backlight unit. Thus, there may be provided a backlight unit with enhanced light efficiency and image quality in the area around the light source and a display device including the same.
