Abstract: A plasma display panel capable of preventing faulty discharge and non-uniform discharge by applying a uniform address voltage to all subpixels. This is done by neutralizing the negative surface potential of a zinc silicate green fluorescent material using YBO3:Tb as a positive surface potential material on the partition walls between the electrodes. Also, the thickness of this YBO3:Tb material and a lateral spacing between a scan electrode and the positive surface potential material are carefully selected to arrive at a design resulting in no faulty pixels. Grooves can also be formed in the tops of the partition walls so that the positive surface potential material filled therein does not mix with the neighboring flourescent material.
