Sealing structure of field emission display device and method of manufacturing the same

A method of manufacturing a sealing structure of a field emission display device, comprising:

• preparing a lower substrate and an upper substrate;
• installing a frit between the lower substrate and the upper substrate, the frit having at least one exhaust outlet;
• and
• heating the lower substrate and the upper substrate, while arranging the upper substrate on the lower substrate, at a predetermined temperature to melt the frit in order to seal a space between the lower substrate and the upper substrate.

A method of manufacturing a sealing structure of a field emission display device, comprising:

• preparing a lower substrate and an upper substrate;
• forming spacers between the lower substrate and the upper substrate;
• forming a frit separated from the spacers by a predetermined distance, the height of the frit being larger than the height of the spacers by a predetermined length;
• and
• heating the lower substrate and the upper substrate while arranging the upper substrate on the lower substrate, the height of the frit decreasing during the heating having the spacers contact the lower substrate and the upper substrate.
