In an LCD apparatus having a backlight assembly, a light guide plate includes an incident surface for receiving light, a reflecting surface for reflecting the light and an emitting surface for emitting the light. A linear distance between the reflecting and emitting surfaces is smaller than a height of the incident surface. An optical sheet is positioned at the emitting surface having a height lower than the height of the incident surface. Accordingly, although the height of the incident surface increases, the linear distance between the reflecting and emitting surfaces does not increase. Therefore, the light guide plate can obtain an area of the incident surface appropriate to efficiently receive the light, thereby improving a light efficiency of the backlight assembly and preventing an increase in a thickness of the backlight assembly.
