Patent ID: 7425797

Claim:
A plasma display panel, comprising: a first substrate and a second substrate provided opposing one another with a predetermined gap therebetween; address electrodes formed on the second substrate; barrier ribs mounted between the first substrate and the second substrate, the barrier ribs defining a plurality of discharge cells; phosphor layers formed within the discharge cells; and discharge sustain electrodes formed on the first substrate, wherein the discharge sustain electrodes include bus electrodes that extend such that a pair of the bus electrodes is provided for each of the discharge cells, and protrusion electrodes extending from and forming an angle different from right angle with each of the bus electrodes such that a pair of opposing protrusion electrodes, one member of the pair being a mirror image of the other, is formed within an area corresponding to each said discharge cell and wherein a distal end of each of the protrusion electrodes opposite a proximal end connected to and extending from the bus electrode includes an indentation at a center area thereof such that a gap is formed between the pair of opposing protrusion electrodes, and an aperture is formed in each of the protrusion electrodes to thereby increase an aperture ratio of the protrusion electrodes.
