ABSTRACT A LCD area includes a flat-design housing having at least one line of display elements forming the front of the housing and a backlighting device disposed inside the housing and assigned to the line of display elements. The heat load of the LCD display elements is reduced and the construction of the housing is simplified by providing the backlighting device with a light-guide tube disposed inside the housing and a light source disposed at a light entrance opening of the light-guide tube made from transparent material and surrounded by a reflector material, which comprise cutouts assigned to the individual display elements and serve as light-exit openings.
