Abstract: Embodiments of the present disclosure relates to a light path control element, a backlight unit and a display device, and by disposing, over one or more light sources, a light path control element including a first engraved patterns located on a surface through which light exits and located to correspond to respective light sources, and a second engraved patterns located on a surface into which light is incident and located in an areas between light sources, it is possible to improve functions of guiding and diffusing light emitted from the light sources. Accordingly, by increasing a distance between light sources and enabling a hot spot to be prevented and luminance uniformity to improve, it is possible to reduce the number of light sources and provide a backlight unit producing improved image quality.
