1. 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.
