Patent ID: 7211953

Claim:
A plasma display device comprising: a first substrate; an address electrode on a surface of said first substrate; a first dielectric layer on the surface of said first substrate and in which said address electrode is embedded; a second substrate coupled to said first substrate; a plurality of maintaining electrodes on a surface of said second substrate forming an angle with said address electrode, each of said maintaining electrodes including first and second electrodes; a second dielectric layer on said second substrate and in which said maintaining electrodes are embedded, wherein said second dielectric layer includes a groove having a discontinuous pattern, located at least partially between said first and second electrodes, and varying the thickness of said second dielectric layer; and partitions located between said first and second substrates defining respective discharge spaces between closest pairs of said partitions, wherein thickness of said second dielectric layer varies with position on said second substrate and said second dielectric layer has minimum thicknesses within respective discharge spaces.
