Plasma display device and method of manufacturing dielectric layer having portion where electrical field is concentrated

A plasma display device comprising:

• a first substrate;
• an address electrode formed on an upper surface of said fist substrate;
• a first dielectric layer formed on the upper surface of said first substrate and embedding said address electrode;
• a second substrate which is transparent and forms a discharge space by being coupled to said first substrate;
• a plurality of maintaining electrodes formed on a lower surface of said second substrate to form a predetermined angle with said address electrode, each of said maintaining electrodes including first and second electrodes;
• a second dielectric layer formed on said second substrate where said maintaining electrodes are formed and embedding said maintaining electrodes;
• at least one portion where an electrical field is concentrated formed at an area corresponding to said first and second electrodes constituting said maintaining electrodes;
• and
• a partition installed between said first and second substrates for sectioning the discharge space.

A method of manufacturing a dielectric layer having a portion where an electrical field is concentrated of a plasma display device, said method comprising the steps of:

• forming a plurality of maintaining electrodes on an upper surface of a substrate, each of said maintaining electrodes being constituted by a pair of first and second electrodes;
• forming a lower dielectric layer on an upper surface of said substrate where said maintaining electrodes are formed;
• printing an upper dielectric layer for forming a groove in a continuous or discontinuous pattern at a portion on an upper surface of said lower dielectric layer and between said first and second electrodes;
• and
• curing said upper and lower dielectric layers by burning the same.

A method of manufacturing a dielectric layer having a portion where an electrical field is concentrated of a plasma display device, said method comprising the steps of:

• preparing a transparent substrate;
• forming a plurality of maintaining electrodes on an upper surface of said substrate, each of said maintaining electrodes being constituted by a pair of first and second electrodes;
• forming a dielectric layer on the upper surface of said substrate where said maintaining electrodes are formed;
• softening said dielectric layer by heating the same at a predetermined temperature;
• and
• forming a groove in said softened dielectric layer by pressing a mold having a protrusion of a pattern corresponding to that of said groove to be desired against an upper surface of said softened dielectric layer.
