Zusammenfassung:	Some embodiments of the present disclosure relate to a backlight unit and a liquid crystal display device, in a case where an edge area of a cover bottom is formed in an inclined structure, a reflective unit, such as a reflective sheet, forming a step structure is disposed in the boundary between a bottom surface and an inclined surface of the cover bottom, and thus a sufficient amount of light can be uniformly supplied to a lower portion of the panel corresponding to an edge area of the cover bottom. In addition, since a light absorption pattern is applied to a step structure of the reflective unit, a bright line resulted from concentrating of the light reflected from the step structure of the reflective unit, in a specific area is prevented and improved luminance and uniformity of light can be provided in an area of the panel corresponding to an inner side of the inclined surface and the inclined surface of the cover bottom.
