Abstract: A bonding method using a bonding agent is provided, which has the steps of forming an underlayer on a first member, providing a bonding agent on the underlayer, forming a contact member, different from the bonding agent, on a second member, bringing the bonding agent into contact with the contact member so that the first member and the second member are bonded to each other. In the method described above, the wettability of the bonding agent to the underlayer is superior to that of the bonding agent to a surface of the first member before the underlayer is formed thereon, and the bondability of the bonding agent to the contact member is superior to that of the bonding agent to a surface of the second member before the contact member is formed thereon.

Abstract: A manufacturing method of a vacuum airtight container includes a baking step of baking, in a vacuum atmosphere, a container in which a first non-evaporable getter and a second non-evaporable getter having an activation temperature higher than that of the first non-evaporable getter are disposed. The baking step further includes steps of baking the entire container by increasing the temperatures of the container to a temperature T1 and holding the temperature T1, which is equal to or higher than an activation temperature of the first non-evaporable getter and is lower than an activation temperature of the second non-evaporable getter. After holding the temperature T1, the entire container is baked by increasing the temperature of the container to a temperature T2, which is higher than the activation temperature of the second non-evaporable getter.

Abstract: Under a vacuum atmosphere, while keeping two members in contact with each other with a bonding material therebetween, one of the members is moved relative to the bonding surface in the horizontal direction, and the bonding material between the members is pressed. The surface oxide film of the bonding material, which is a low melting point metal, is thereby broken effectively, and highly hermetic bonding is performed.

Abstract: A bonding member, which can achieve a sufficient degree of vacuum without forming a gap caused by air bubbles that have been released out through the surface of the bonding member, a bonding method, an image display apparatus, and a manufacturing method therefor. The bonding member 92 of a strip has a first portion 92a and a second portion 92b. The first portion 92a has a uniform thickness t1. The second portion 92b has a smaller thickness t2 than the thickness t1 of the first portion 92a and constitutes a side plane of the bonding member 92. The second portion 92b also has a shape such that a convexity and a concavity alternate along a longitudinal direction of the bonding member 92.

Abstract: To provide a method of manufacturing a vacuum airtight container, capable of activating a non-evaporable getter having a different activation temperature, without providing a process of giving external energy other than heat to be used in a baking process, the method of manufacturing the vacuum airtight container according to the present invention includes STEP 2 of activating only a first NEG by increasing a temperature in a decompression atmosphere up to a temperature T1 at which the first NEG is activated, and also includes STEP 4 of activating, after activating the first NEG, a second NEG by increasing the temperature in the decompression atmosphere up to a temperature T2 at which the second NEG is activated. The STEP 2 and the STEP 4 end in a baking step.

Abstract: A joining material like an In film having a low melting point forms a surface oxide film when melted. If the oxide film is thick, an uneven surface shape will remain as it is, and can cause vacuum leakage during vacuum sealing. This problem is solved, for example, by placing particles of a refractory material inside the low melting joining material. The particles of the refractory material serve as a holding member for the low melting material and break the oxide film during a joining operation to bring the seal bonding with the low melting material to perfection.

Abstract: In an image display device having in an airtight container an electron source and an image display member that receives electrons from the electron source, an evaporating getter and a non-evaporating getter are stacked in the airtight container. This makes it possible to maintain the vacuum level in the airtight container. The image display device thus obtains a prolonged life and a stable display operation.

In particular, in such a configuration, the substrate or the frame has a first region and a second region which are brought into contact with the low melting point metal, and in the first region, a material capable of higher maintaining airtightness with the low melting point metal than the second region is in contact with the low melting point metal, while in the second region, a material having a stronger binding power on the low melting point metal than the first region is in contact with the low melting point metal.

Abstract: In a recycling method for an image display apparatus including a vacuum container structured by sealing a front panel having a phosphor and a rear panel having an electron emitter for irradiating electrons onto the phosphor, the rear panel is separated from the vacuum container, the electron emitter on the rear panel is recovered, and then the rear panel is sealed again to thereby reconstruct the vacuum container.

Abstract: An image display device comprises: a front substrate having a fluorescent member for displaying an image, and a metal back for covering the fluorescent member; a rear substrate having an electron emission element; and a support frame disposed between the front substrate and the rear substrate. In the image display device, a thickness of the metal back is 55 nm or more and 120 nm or less, and at least the metal back is covered with a getter. Thus, since the metal back of the front substrate is covered with the getter, a time-dependent deterioration of luminance is small and a lifetime is long even if a potential of the metal back is high.
