Description of the Related Art A conventional general fluorescent display device has a cathode for emitting electrons inside an envelope in a high vacuum state, and further has an inner surface of the envelope facing the cathode. Has a display section having a phosphor layer and an anode conductor. A control electrode is provided between the cathode and the display unit in the envelope as needed. Then, electrons emitted from the cathode are selectively projected on the phosphor layer to perform desired light emission display. As a cathode of the fluorescent display device, a cold cathode such as a field emission cathode is used in addition to a linear cathode which emits thermoelectrons when energized and heated. Further, generally, the envelope of the fluorescent display device, a substrate on which a display unit is formed,
It is formed of a facing plate facing the substrate and side portions forming side surfaces of the envelope. When forming the envelope, the inside of the envelope is evacuated from an exhaust pipe or an exhaust hole provided on the substrate or the facing face plate, and then the exhaust pipe is sealed or the exhaust hole is closed with a lid member or the like. It is sealed and the inside is kept in a high vacuum state. In addition, an exhaust pipe may be provided on the side surface, and the inside may be exhausted and sealed via the exhaust pipe.

ないという問題があった。When the inside of the envelope is evacuated from the substrate or the opposing face plate, the substrate or the opposing face plate may be sealed using either an exhaust pipe or a lid member. Exhaust holes must be formed in When the exhaust holes are formed in the substrate as described above, there are problems such as dust generated during the processing, contamination during the process, cracks generated in the substrate and the like. In particular, when fine processing is required for both the substrate and the facing plate, such as in a fluorescent display device using a field emission cathode, contamination caused by the formation of exhaust holes may adversely affect the fine processing. In addition, there has been a problem that the exhaust holes themselves have an adverse effect on the exposure step of fine processing and the like, so that precise processing cannot be performed.

いう問題があった。In addition, if an exhaust pipe is provided on the side surface of the hermetic envelope, the thickness of the fluorescent display device cannot be reduced. For this reason, for example, in a fluorescent display device of a type in which a planar cathode such as a field emission cathode is formed on the inner surface of the opposed face plate, even if an attempt is made to select a display area using the cathode, the distance between the cathode and the display unit is limited. Because of the large size, there is a problem that electrons are diffused and good display cannot be obtained. In the fluorescent display device, a getter material is used to increase the degree of vacuum inside the envelope. Therefore, a space is required in the envelope of the fluorescent display device to scatter the getter and form a getter film, and the thickness of the fluorescent display device body is reduced as in the case where the exhaust pipe is provided on the side surface. There was a problem that it was not possible.
