Abstract
A sealing glass composition for bonding the upper plate and the lower plate of a flat panel display device is described. The sealing glass composition includes a low melting point glass containing PbO of less than 20% and having a sintering temperature of less than 500° C. The sealing glass composition contains a low component of PbO to thereby decrease environmental contamination and increase work efficiency. Also, the sealing glass prevents the deformation and cracking of a substrate caused by thermal and mechanical stress and reduces the sintering temperature to thereby enhance the airtightness of the sealing glass.
