A backlight assembly for an LCD apparatus comprises a lamp emitting light; a light guide plate including a light-entering surface through which the light from the lamp enters, and a light-emitting surface through which the light is emitted; a lamp reflector having an opening toward the light-entering surface and combined to the light guide plate, accommodating and covering the lamp; and a light interceptive part interposed between the light-emitting surface and the lamp reflector, and preventing the light from the lamp from entering through an edge at which the light-entering surface and the light-emitting surface are intersected. With this configuration, the present invention provides a backlight assembly for an LCD apparatus, which is improved in preventing a bright-line occurring on a front area adjacent to a light-entering surface of a light guide plate and in enhancing the brightness.
