ができるようになる。Next, the operation will be described. The basic principle of this type of display device is to accelerate the thermoelectrons emitted from the cathode and cause them to collide with the anode, thereby exciting the phosphor applied on the anode surface to emit light. In FIG. 17, the thermoelectrons emitted from the cathode behave as follows due to the combination of the potentials of the first control electrode (hereinafter referred to as scan electrode) and the second control electrode (hereinafter referred to as data electrode). Each is shown in association with FIG. (1) When both the scanning electrodes connected in the row direction and the data electrodes connected in the column direction are positive with respect to the cathode, the electrons emitted from the cathode due to the positive potential of the data electrode depend on the potential of the scanning electrode. The light is deflected, passes through a predetermined opening, reaches the anode, and causes the phosphor to emit light. (2) When the scan electrode is positive and the data electrode is negative, the potential near the cathode becomes negative due to the negative potential of the data electrode near the cathode, and the emission of thermoelectrons is suppressed. Therefore, the phosphor does not emit light. (3) When the scanning electrode is negative and the data electrode is positive, there are two cases as follows. a. When the other scan electrode is positive, thermions emitted from the cathode are deflected to the other scan electrode by the potential of the scan electrode, and the phosphor does not emit light. b. When the other scan electrode is also negative, the potential of the data electrode is positive, but since the area of the data electrode is small, the vicinity of the cathode becomes negative due to the negative potential of the scan electrodes on both sides, and the emission of thermionic electrons occurs. It is suppressed and the phosphor does not emit light. (4) When both the scanning electrode and the data electrode are negative, the potential near the cathode becomes negative, the emission of thermoelectrons is suppressed, and the phosphor does not emit light. As a result, the row (scanning) electrode to which a positive potential is applied is determined by the relationship between the wiring relationship in FIG. 14 and the pixel arrangement in FIG.
And the phosphor located at the intersection of the column (data) electrodes emits light. First, when a signal is applied to the S _1, P
₁₁ to P ₁₄ are selected, these data electrodes (D ₁ ~D ₄₎
Emit light according to the potential of Next, when signal S ₂ is applied, P ₂₁ to P ₂₄ is selected, also emit in accordance with the potential of the data electrodes. In this manner, as shown in FIG. 15, by applying a scanning signal sequentially to the scanning electrodes and applying an arbitrary data signal to the data electrodes, an arbitrary display can be obtained.

ディスプレイの高解像度化が困難であった。The conventional light-emitting device has the above-described structure and operation principle, and a large-screen display is constructed by arranging a large number of light-emitting devices. Here, since this type of light emitting element has a vacuum inside, it must withstand atmospheric pressure, and the thickness of the plate material constituting the glass container cannot be reduced. Therefore, there is a problem that the weight of the light emitting element increases. In order to further increase the resolution, it is necessary to reduce the pitch between pixels, and for this purpose, it is necessary to reduce the thickness of the spacer. To reduce the thickness of the spacer should be strengthened vessel but, as in the real-Open No. 1-62643 as a countermeasure therefor, a method to make a post on the inside of the light emitting element is known. However, in reality, the deformation size of the column portion in the light emitting element due to atmospheric pressure is very small, on the order of 10 μm, but the dimensional accuracy of the spacer is inferior to the order of 100 μm, and does not serve as a column. There was a problem. For this reason, when arranging the light emitting elements, it is necessary to provide a gap of approximately twice the thickness of the spacer between the pixels, which has been an obstacle to shortening the pixel pitch. For this reason,
High-resolution of the display is difficult.

(a) is a cross-sectional view of the entirety, and (b) is an enlarged view of part A of the same figure.
(c) is a bottom view, and (d) is a perspective view of only the exhaust glass tube. In this type of light emitting device, the front and rear panels 1a and 1c are the largest in area and are susceptible to atmospheric pressure, so that the central portion is depressed toward the inside of the container. Therefore, it has been conventionally proposed to provide a column in this portion to suppress dents due to atmospheric pressure (for example, Japanese Patent Application No. 4-334018). The problem is how to set up the pillars, and the actual production method. By the way, in the present invention,
First, as shown in FIG. 1 (a), the light emitting element is placed upside down, that is, with the front panel 1a down and the back panel 1c up,
An exhaust glass tube 15 having a notch 15a, which is an exhaust opening at the tip, is inserted through the exhaust port 10 at the center of the back panel 1c. The exhaust glass tube 15 also plays a role of insulating protection of the high-voltage lead wire, but has no relation to the present invention, so that the high-voltage lead wire is not shown. Therefore, what is important at this time is that the glass tube 15 is inserted by gravity until the front end of the glass tube 15 hits the front panel 1a. In this way, the exhaust glass tube 1 is placed with the front panel 1a facing down.
5 through the exhaust port 10 of the rear panel 1c.
After it is inserted until it hits a, and it is confirmed that it hits, the middle part of the exhaust glass tube 15 is bonded to the middle part of the exhaust glass tube 15 at the location of the rear panel exhaust port 10 with a glass adhesive 20 called frit glass. By doing so, the exhaust glass tube 15 can be easily mounted between the front and rear panels without considering the difference in the distance between the front panel 1a and the rear panel 1c (or manufacturing variation). It becomes possible.

Glass tube 15
The frit glass bonded portion 20 is not peeled off. In order to achieve the above object, a thin circular frit glass 20a or the like is previously set in a portion of the front panel 1a where the exhaust glass tube 15 contacts, or the frit glass 20a is thinly applied in advance. With such a configuration, the exhaust glass tube 15 is bonded not only with the back panel 1c and the frit glass 20 but also with the front panel 1a with the precoated frit glass 20a, thereby further strengthening.
