Abstract: A color plasma display panel including a pixel matrix array (R, G, B) in which discharge cells of the red (R), green (G) and blue (B) are grouped to constitute a pixel, wherein the pixel includes a blue discharge cell (B) having a height smaller than the entire height of the pixel and width equal to entire width of the pixel (R, G, B), and red and green discharge cells laterally aligned with each other, each of the red and green discharge cells having a height corresponding to a difference between the entire height of the pixel and the height of the blue discharge cell (B) and a width less than 1/2 the entire width of the pixel. The pixel further includes an assistant cell (M) disposed between the red and green discharge cells and priming holes (H) respectively provided at partition walls each disposed between each of the red (R) and green (G) discharge cells and the assistant cell (M).
