ABSTRACT:
A backlight unit capable of being designed in consideration of both thermal expansion of optical sheets and positioning accuracy of the optical sheets on a backlight chassis. The backlight unit is arranged behind a display panel and includes a backlight chassis arranged to house a lamp, which includes a support surface arranged to support optical sheets, and a frame arranged to hold the optical sheets with the support surface of the backlight chassis, the optical sheets being interposed between the frame and the support surface, wherein the backlight chassis has, on its support surface, a positioning piece arranged to position the optical sheets at a predetermined position with respect to the support surface, and a position of the positioning piece corresponds to an approximate center of a longer edge of the optical sheets.
