Abstract: A color conversion plate and a display device are disclosed. Since a color conversion plate including a color conversion area and a transmissive area separated by a reflection barrier rib is in the path where light is supplied to the color filter, efficiency and purity of light supplied to the color filter is enhanced and the color gamut of the light emitted to the outside of the display device through the color filter is also enhanced.

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.

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.
