Abstract

The invention relates to an electro-optical flat-design display device, in particular to an LCD area, comprising a flat-design housing 1 having at least one line of display elements 10 forming the front 8 of the housing 1, and comprising a backlighting device disposed inside the housing 1 and assigned to the line of display elements 10. For reducing the heat load of the LCD display elements 10 and for simplifying the construction of the housing 1, it is provided, according to the invention, that the backlighting device includes a light-guide tube 12, 17 disposed inside the housing 1 and a light source 18 disposed at a light entrance opening of the light-guide tube 12, 17, that the light-guide tube 12 is made from transparent material and surrounded by a reflector material 14, and that the reflector material 14 comprises cutouts 15 assigned to the individual display elements 10 and serving as light-exit openings FIG. 2.
