Abstract
A plasma display panel in which the reliability of seal bonding of a chip tube is assured and an evacuation working efficiency is improved. In a plasma display panel with a structure in which a glass substrate on the display surface side and a glass substrate on the rear side are adhered so as to be hermetically bonded by sealing layers through partitions and a gas is introduced into the space between the two glass substrates, an evacuation and gas charging hole is formed in one of the glass substrates and crystalline glass powder of a low melting point is molded into a predetermined shape and is baked, thereby seal bonding the chip tube into the evacuation and gas introducing hole.
