Patent ID: 7999473

Claim:
A plasma display panel comprising: first and second substrates; first and second elements, each having a first height and a first width, wherein the first and second elements are located between the first and second substrates so as to engage the first substrate; third and fourth elements, each having a second height and a second width, wherein the third element is located on the first element and the fourth element is located on the second element, and wherein the first width is greater than the second width wherein the third and fourth elements are separated by a distance equal to Lp; a discharge cell defined at least between the third and fourth elements; another third element adjacent to the fourth element, the fourth element and the other third element defining a non-discharge space therebetween; a dielectric layer formed on the first substrate, wherein the dielectric layer is exposed to the non-discharge space; and a fluorescent layer formed on the dielectric layer between the first and second elements, wherein a surface of the first element facing the second substrate and facinig the discharge cell has a width Ws, wherein Ws is greater than about 0.15 times Lp and is less than about 0.33 times Lp.
