Abstract
In a plasma display panel, red, green, and blue pixels have the same voltage range for write discharges. The red, the green, and the blue pixels have first, second, and third data electrodes, respectively, covered with an insulating film. A red fluorescent substance layer is formed on the insulating film over the first data electrode. A green fluorescent substance layer is formed on the insulating film over the second data electrode. A blue fluorescent substance layer is formed on the insulating film over the third data electrode. The green fluorescent substance is smaller than both of the red and the blue fluorescent substance layers in thickness.
