Abstract: A plasma display device having a face plate and a rear plate spaced apart from each other. Parallel sustaining electrodes are arranged preferably on the face plate, while parallel address electrodes are arranged preferably on the rear plate, so that they are spaced apart from and extend perpendicularly to the sustaining electrodes. Barrier ribs are disposed to define discharge gas spaces adjacent to crossovers of the electrodes. At least some of the barrier ribs are transparent barrier ribs made of a light-permeable material, so that, particularly when the rear plate is covered with a reflective layering, light which might otherwise leak from the rear plate is usefully saved and caused to radiate through the face plate, whereby the use ratio of the emitted light increases.
