  • Patent number: 7473023
    Abstract: A backlight assembly includes a lamp assembly generating light, a light guide plate changing a path of light incident from the lamp assembly, a receiving container having a bottom part and a side part vertically extending from the bottom part and forming a receiving space, and an adhesive member fixing the light guide plate to the receiving container. The light guide plate includes a prism pattern on a surface, and the adhesive member is attached to a light-adjusting portion opposite to the lamp assembly. Therefore, the light guide plate may be affixed to the receiving container without additional structure and the appearance of the backlight assembly may be improved by preventing modification of the prism pattern.
