Abstract
A flat display panel and a flat display device are realized in which sealing layers can sufficiently alleviate and absorb strain stress between two substrates which is caused by internal stress of the substrates during sealing process and after cooling process, and which can cancel out disadvantages of an amorphous glass paste and a crystallized glass paste, and a flat display panel manufacturing method is realized which can prevent application of excessive or insufficient pressure to the sealing layers. In a flat display panel formed with at least two substrates ( A) and ( B) sealed together, sealing layers ( ) are formed as a stacked structure containing a plurality of layers or formed in a region containing a plurality of stripes, so as to obtain a stable seal. The sealing layers ( ) are formed of a crystallized glass paste ( A) and an amorphous glass paste ( B). A pressing force applied in the sealing process is positioned near the sealing layers and inside the position of the sealing layers.
