AIR TIGHT CONTAINER AND METHOD OF MANUFACTURING IMAGE DISPLAY UNIT

PROBLEM TO BE SOLVED: To provide a method of manufacturing a highly reliable air tight container which combines bonding strength and airtightness.SOLUTION: A bonding material 1a having viscosity of negative temperature coefficient and a softening point lower than that of first and second glass base materials 14 and 13 is formed in the shape of a frame on the first glass base material 14, and the second glass base material 13 is arranged to face the first glass base material 14 on which the bonding material 1a is formed so that the second glass base material 13 comes into contact with the bonding material 1a. Irradiation of local heating light is performed so that at a boundary 52 between a first region 50 of the bonding material 1a irradiated with the local heating light and a second region 51 of the bonding material 1a adjacent to the first region 50 and not irradiated with the local heating light, a part of the second region 51 adjacent to the boundary 52 is heated and melted while the viscosity of the bonding material 1a at a part 53 of the first region 50 adjacent to the boundary 52 is 10(Pa*sec) or less.
