Abstract

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 frame 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 integrally 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. A lamp can be exchanged by simply separating the second frame from the mold frame, so the fault of the light source caused by the friction with other elements is reduced when exchanging the lamp.
