Abstract:
A plasma display device illuminating in three primary colors comprising,an insulating back plate as a substrate, a plurality of partition walls on the insulating back plate, the partition walls being substantially parallel to one another and defining light emitting cells; a transparent front plate mounted on the partition walls, fluorescent substance layers for the three primary colors on the partition walls in the light emitting cells, wherein a light emitting cell having a fluorescent substance layer for one primary color is adjacent to light emitting cells having fluorescent substance layers for the remaining two primary colors; discharge electrodes in each cell which are attached on the rear side of the transparent front plate, and rare gas filled in all the light emitting cells, and wherein sizes of the light emitting cells of the three primary colors are made different according to a luminance of the fluorescent substance of the corresponding primary color, thereby making the maximum luminance on the display image substantially equal among the three primary colors.
