Plasma display panel having trench type discharge space and method of fabricating the same

A plasma display panel having first and second substrates, comprising:

• a plurality of UV visible photon conversion layers on the first substrate;
• a plurality of barrier ribs between each of the UV visible photon conversion layers;
• a first electrode on the second substrate;
• a first dielectric layer on the second substrate including the first electrode;
• a plurality of second electrodes completely buried in the first dielectric layer;
• a second dielectric layer on the first dielectric layer;
• and
• a discharge chamber between the first and second substrates defined by the barrier ribs connecting the first and second substrates, wherein the first dielectric layer has at least one trench type discharge space exposing a portion of the first electrode to the discharge chamber.

A method of fabricating a plasma display panel having first and second substrates, the method comprising the steps of:

• forming a first electrode on the first substrate;
• forming a first dielectric layer on the first substrate including the first electrode;
• forming a plurality of second electrodes in the first dielectric layer, the second electrodes being completely buried in the first dielectric layer;
• forming a second dielectric layer on the first dielectric layer including the second electrodes;
• forming a reflection layer on the second substrate;
• forming a UV visible photon conversion layer on the reflection layer;
• forming at least one trench type discharge space in the first and second dielectric layers exposing a portion of the first electrode in the trench type discharge space to the UV visible photon conversion layer;
• and
• forming a plurality of barrier ribs connecting the first and second substrates, thereby defining a discharge chamber between the first and second substrates.
