Backlight assembly using the same and liquid crystal display device

摘要

There are provided a backlight assembly ( 700 ) and an LCD device ( 1000 ) using the same. The backlight assembly ( 700 ) has an optical sheet ( 100 ) for improving light efficiency and optical properties thereof and an elastic adhesive member ( 130 ) disposed on the optical sheet ( 100 ). When the optical sheet ( 100 ) deforms with heat, the elastic adhesive member ( 130 ) may be expanded or contracted corresponding to deformation of the optical sheet ( 100 ) and absorb impact applied to LCD device. Accordingly, the backlight assembly ( 700 ) may prevent the optical sheet ( 100 ) from being wrinkled or scratched, thereby preventing display quality of the LCD device from being deteriorated.
