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.

摘要： There is disclosed a backlight assembly for maximizing a light incidence efficiency by changing a construction of a light guide plate and a liquid crystal display device having the same. A light incidence surface of the light guide plate receiving a light from a lamp is inclined to make an obtuse angle with a light-emitting surface through which the light is transferred to the display unit. An open surface of a lamp cover that is disposed to face towards the light incidence surface is formed to have the same inclined angle as the light incidence surface of the light guide plate. In addition, a light reflecting plate and an optical sheet are respectively disposed on the top and bottom surfaces of the light guide plate, on which light absorbing layers, for absorbing light that leaks from the light guide plate, are formed at both ends thereof. Accordingly, there are advantages in that the light incidence efficiency of the light is improved even though a thickness of the light guide plate is not increased, and that it is possible to remove the light concentrated at an edge of the light incidence surface of the light guide plate.

摘要： A liquid crystal display has a mold frame divided into several parts. The liquid crystal display device includes a display unit for displaying an image, a back-light assembly having a light source for generating a light, a light guiding plate for guiding the light, and a light focusing portion for focusing the light, and a mold divided into a first frame and a second frame. The mold frame receives the display unit and the back-light assembly. The first frame receives the light guiding plate and the light focusing portion and the second frame receives the light source. A reflection sheet is integral formed at an inner surface of the second frame so as to perform the function of a lamp reflector. Accordingly, a lamp cover is not required so that the number of parts and the manufacturing cost are reduced.
