A front frame of a flat panel display having positioning structure allows a LCD cell to be positioned and mounted thereon along an assembly direction. A restraining frame may be further incorporated for positioning and spacing purposes for each component of the display. Optical films, a light guide component, a backlight unit, and a reflector of the flat panel display are then mounted in a row along the assembly direction on the restraining frame or the front frame, where the backlight unit and/or the reflector may be fixed to a back cover of the backlight module in advance. Finally, a speaker, wiring of the display, circuit boards, and a board cover are assembled to the front frame and the back cover.
