An LCD apparatus has a first lamp unit, a light guide unit, and a receiving container. The first lamp unit has a first light generating portion and a second light generating portion integrally connected with the first light generating portion. The light guide unit has side surfaces for receiving light from the first lamp unit, a reflecting surface for reflecting the light input through the side surfaces, and an emitting surface for emitting the light input through the side surfaces and reflected from the reflecting surface. The receiving container has a bottom and sidewalls each extended from the bottom and facing corresponding one of the side surfaces of the light guide unit, for receiving the first lamp unit and light guide unit. Further the receiving container is configured to have a plurality of parts separate from each other to withdraw the first lamp unit from the receiving container.
