Patent ID: 7323819

Claim:
A plasma display panel comprising: a rear substrate; a plurality of address electrodes arranged on a surface of the rear substrate; a rear dielectric layer arranged on the rear substrate to cover the address electrodes; a plurality of barrier ribs adapted to define discharge cells, the plurality of barrier ribs arranged on an upper portion of the rear dielectric layer; a fluorescent material adapted to coat an inner surface of the discharge cells; a front substrate arranged to face the rear substrate; a plurality of sustain electrode pairs, each pair composed of X and Y electrodes adapted to form unit discharge cells and to cross the address electrodes and arranged on a lower surface of the front substrate; a light absorption reflection film including a first light absorption reflection film arranged between adjacent sustain electrode pairs on a lower surface of the front substrate and a second light absorption reflection film having a different width than that of the first light absorption reflection film, the second light absorption reflection film arranged on a lower surface of the first light absorption reflection film; and a front dielectric layer arranged on a lower surface of the front substrate to cover the X and Y electrodes and the light absorption reflection film; wherein the first light absorption reflection film and the second light absorption reflection film are arranged to have a stair shape having a step difference; and wherein when the greater of the widths of the first and second light absorption reflection films is A and the narrower width is B, a value of (A−B)/A×100 is in a range of 5-70.
