In a flat panel display device, a display panel for displaying an image is disposed on a mold frame and supported by a metal clip coupled to the mold frame. The metal clip includes a first coupling portion coupled to an upper surface of the mold frame, a second coupling portion coupled to a lower surface of the mold frame, a connecting portion for connecting the first and second coupling portions and a guiding portion upwardly extended from the connecting portion so as to guide and support the display panel. Accordingly, the flat panel display device can have a reduced size and an enhanced assemblability.
