Abstract: A method for manufacturing a glass panel unit, which reduces the amount of a getter material to enable a gettering ability to be realized at a relatively low temperature less likely to cause damage. The method includes a step of producing a getter material by heating an unprocessed getter material at a temperature higher than a prescribed temperature Te; a step of producing a preassembled component including a first and second glass pane, a heat-fusible sealing material, an internal space, and a gas adsorbent containing the getter material, and an evacuation port; a step of forming a frame body hermetically bonding the first glass pane and the second glass pane together by melting the heat-fusible sealing material with heat; and a step of heating the gas adsorbent at the prescribed temperature Te while the internal space is evacuated by exhausting air in the internal space through the evacuation port.

Abstract: A glass panel unit includes: a first panel including a glass pane; a second panel including another glass pane; a sealing portion; an exhaust port; and a printed portion. The second panel is arranged to face the first panel. The sealing portion is formed in a frame shape and hermetically bonds respective peripheral edge portions of the first and second panels to create an evacuated, hermetically sealed space between the first panel and the second panel. The exhaust port is provided for one panel selected from the first and second panels. A port sealing member hermetically seals the exhaust port. The printed portion is provided for the other panel selected from the first and second panels. The printed portion is located in an area, facing the exhaust port, of one surface of the other panel. The one surface either faces toward, or faces away from, the hermetically sealed space.

Abstract: A method for manufacturing a glass panel unit includes a glue arrangement step, an assembly forming step, a first melting step, an evacuation step, and a second melting step. The first melting step includes melting a hot glue, bonding a first and second panel with the glue, and forming an internal space. The first melting step includes a first temperature raising step, a first temperature maintaining step including maintaining the temperature of the assembly at a temperature equal to or higher than a softening point of the hot glue, and a first temperature lowering step, which are performed in this order. The first temperature lowering step includes: an anterior temperature lowering step including lowering the temperature of the assembly; a middle temperature maintaining step including maintaining the temperature of the assembly; and a posterior temperature lowering step including lowering the temperature of the assembly, which are performed in this order.

Abstract: A glass panel unit assembly includes: a pair of glass substrates arranged to face each other; a peripheral wall; a partition; an air passage; and an evacuation port. The peripheral wall has a frame shape and is disposed between the pair of glass substrates. The partition partitions an internal space, surrounded with the pair of glass substrates and the peripheral wall, into a first space and a second space. The air passage connects the first space and the second space together. The evacuation port connects the second space to an external environment. The partition is lower in height than the peripheral wall.

Abstract: A glass panel unit includes: a sealing member arranged between a first panel and a second panel, which are arranged to face each other with a predetermined gap left between themselves, to hermetically bond the first panel and the second panel together; and an internal space sealed hermetically with the first panel, the second panel, and the sealing member. The glass panel unit further includes a spacer arranged in the internal space so as to be in contact with the first panel and the second panel. The spacer includes a plurality of resin layers that are stacked one on top of another in a direction in which the first panel and the second panel face each other. At least any two of the plurality of resin layers have different elastic moduli.

Abstract: An assembly includes a plurality of partitions to partition an internal space, surrounded with a pair of glass substrates arranged to face each other and a the peripheral wall having a frame shape and provided between the pair of glass substrates, into an evacuation space and a ventilation space. The plurality of partitions includes a first partition and a second partition, of which lengths are defined in two different directions. An end of the second partition faces a side portion of the first partition with a predetermined gap left between them. A space between the end of the second partition and the side portion of the first partition constitutes an air passage to evacuate the evacuation space through an evacuation port. The second partition includes, at the end thereof, a swollen portion protruding toward the evacuation space at least along the width of the second partition.

Abstract: A manufacturing method of a glass panel unit of the present invention includes a bonding step, a pressure reduction step, and a sealing step. In the bonding step, a first substrate and a second substrate are hermetically bonded together with a seal having a frame shape. In the pressure reduction step, a pressure in an inside space formed between the first substrate and the second substrate is reduced through an exhaust port. In the sealing step, sealant disposed between the first substrate and the second substrate is deformed, and the sealant thus deformed seals an opening of the exhaust port.
