摘要:
In a method for manufacturing an electron tube including a front substrate and a back substrate, a wiring and an electrode are formed on the front substrate and/or the back substrate. A component is mounted on the front substrate and/or the back substrate. A ring-less getter is mounted on at least one of the front substrate, the back substrate and the component. A vessel is assembled and sealed so that the front substrate faces the back substrate. A light is irradiated on the ring-less getter from outside of the sealed vessel, thereby activating the ring-less getter.

An electron device such as a fluorescent display tube is provided, wherein a simple ring-less getter can be simply fixed and arranged with a large degree of freedom. The ring-less getter, G11 to G13, is securely fixed to the inner surface of the glass anode substrate 111, using laser beams. The laser beam is irradiated onto the ring-less getter, G11 to G13, from outside the anode substrate 111. Thus, the laser beam passes through the anode substrate 111, thus heating and melting the ring-less getter, G11 to G13. The corresponding inner surface of the anode substrate 111 is melted trough the heating. In cooling, the portion where the ring-less getter, G11 to G13, and the anode substrate 111 are in a molten state is solidified, so that the ring-less getter, G11 to G13, is bonded to the anode substrate 111. The ring-less getter, G11 to G13, is shaped arbitrarily through press-working a getter material.

A fluorescent luminous tube is provided that has a getter mirror film formed in an arbitrary shape by illuminating a laser beam onto a getter. In order to form the getter film 32, the rectangular ring-less getter 31 mounted on the anode substrate 11 is irradiated with the laser beam L from the outside of the front substrate 12 and thus is evaporated. In this process, when the illumination spot of the laser beam L is moved along the scanning line 33, the rectangular getter mirror film 32 is formed around the scanning line 33. The burnt region 34, which has the same shape and size as those of the scanning line 33, is formed using the laser beam L.
