Abstract
A plasma display panel is provided which is free from blisters and pinholes on its dielectric layers and has excellent characteristics of breakdown voltage. The plasma display panel has a multilayered first dielectric layer covering a display electrode including a scanning electrode and a sustain electrode that are provided on a front substrate, and a multilayered second dielectric layer covering a data electrode that is provided on a back substrate. The periphery of an upper dielectric layer of the first dielectric layer and/or the second dielectric layer is positioned identically or partially in size and shape to a periphery of a lower dielectric layer to be formed.
Claims1
A plasma display panel comprising:
- a front substrate;
- a back substrate;
- a display electrode provided on said front substrate and formed of a scanning electrode and a sustain electrode;
- a data electrode provided on said back substrate;
- a multilayered first dielectric layer for covering said display electrode, said first dielectric layer including an upper dielectric layer and a lower dielectric layer;
- and
- a multilayered second dielectric layer for covering said data electrode, said second dielectric layer including an upper dielectric layer and a lower dielectric layer;
- wherein at least one of
- a glass softening point of said upper dielectric layer of said first dielectric layer is lower than a glass softening point of said lower dielectric layer of said first dielectric layer, and
- a glass softening point of said upper dielectric layer of said second dielectric layer is lower than a glass softening point of said lower dielectric layer of said second dielectric layer;
- and
- wherein at least one of
- a periphery of said upper dielectric layer of said first dielectric layer is positioned partially in size and shape to a periphery of said lower dielectric layer of said first dielectric layer, and
- a periphery of said upper dielectric layer of said second dielectric layer is positioned partially in size and shape to a periphery of said lower dielectric layer of said first dielectric layer.
