A flat light source having a main region and an edge region around the main region is provided. The flat light source includes a first substrate, first electrodes, dielectric patterns, a phosphor layer, first phosphor patterns, a second substrate, and a sealant. The first electrodes are disposed on the first substrate and arranged within the main region and the edge region. The dielectric patterns cover the first electrodes. The phosphor layer is disposed between the dielectric patterns in the main region and the edge region. The first phosphor patterns are disposed on the phosphor layer within the edge region. The second substrate is disposed above the first substrate, and the sealant is formed out of the edge region between the first and second substrates so as to bond the two substrates.

An front plate structure for a plasma display panel is described. In accordance with the present invention, a protruding space pad structure is formed on the dielectric layer or protective layer of the front plate. The space pad is used to form the height difference on the surface of the front plate, about 3 &#x3bc;m to 15 &#x3bc;m. The height difference forms gas channels between the front plate and the discharge region to improve the performance of the vacuuming and refilling gas steps.
