PURPOSE:To narrow a pitch of adjacent discharge regions and attain high definition by arranging first and second electrodes in partitively formed discharge regions and arranging a third electrode in a dielectric layer so that it faces on the discharge regions. CONSTITUTION:A display device is such constitution that one discharge region partitively formed between a pair of insulation substrates 21, 22 opposite to each other is partitively formed into a plurality of discharge regions P1, P2 by dielectric layers 23b, 23c arranged in one direction, a first electrode (negative electrode) 5 and a second electrode (display positive electrode) 27 are arranged respectively in the discharge regions P1, P2 partitively formed and a third electrode (auxiliary positive electrode) 28 is arranged in the dielectric layers 23b, 23c so as to face on the respective discharge regions P1, P2 partitively formed.

[Detailed Description of the Invention] (Industrial Field of Application) Mokubimei relates to a gas discharge display device δ, which has a particularly simple structure, can be large-sized, can have a 0 viscosity of 11 degrees, and has a relatively high brightness display. The present invention relates to a gas discharge display device that provides the following.

(Prior art) In recent years, with the remarkable development of office automation equipment, display devices such as monitors are required to have even higher definition.For example, flat display devices for high-definition televisions are considered the most promising. This is the discharge display panel.
Research has already reached the point where color display is possible.

There are various types of gas discharge display devices of this type, and each type is being developed with the aim of increasing its size, efficiency, and degree of flitIA. Among them, a good method for achieving the above purpose is a two-substrate gas discharge display device that seals gas between a front transparent insulating substrate and a back transparent insulating substrate and displays an image using glow 11i electricity. are widely adopted.

FIG. 2 shows the above-mentioned two-substrate type gas discharge display M stomach,

The gas discharge display device has a plurality of display discharge areas (discharge areas ii!) defined by a front rolled glass plate 1 and a back glass substrate 2 arranged via a matrix-like dielectric layer 3a. A cathode busbar 4 and a pair of cathodes 5 are arranged on the front glass substrate 1 in this discharge area, while a display anode busbar 6, a pair of display anodes 7 and an auxiliary anode 8 are arranged on the back glass laminated plate 2. each is placed.

The parts of the rear glass bulb 2 other than the display anode 7 are covered with U insulating metal, and a phosphor 9 is placed thereon at /υ surrounding the display anode 4ti7.

And auxiliary anode 8 and negative 4f! The pilot fire discharge generated between the front glass plate 1 and the rear glass LL plate 1 is transmitted through the sulins 1-10 between the dielectric layers 3b and 3c on the light shielding film 11 formed on the front glass layered plate 1 and the back glass LL plate 2. Lead to display discharge area. The auxiliary space 1fi8 may be further constructed by superimposing an auxiliary anode bus bar on this soil.

This display device can be driven in addition to the normal one-row simultaneous IJJ operation, as well as a pulse memory discharge operation by constantly applying a sustain pulse to the display anode 7.

That is, the phosphor 9 existing in the soil of the front glass lj plate 2 is exposed to the ultraviolet rays of R1 by air discharge between the display anode 7 and the cathode 5, and the front glass J
A-plate 1 side l\The light is emitted. Since the scanning pulse is applied so as not to overlap with the sustaining pulse, no pulse discharge occurs in the display discharge area. In addition, display scanning is performed by sequentially applying scanning pulses (voltage or current) to the cathode 5 starting from the ground to cause a pilot discharge between the auxiliary anode 8 and the cathode 5, and during this period, the pilot discharge occurs. By applying a writing pulse (voltage or current) according to the image signal amplitude between the nearby cathode 5 and display anode 7 and emitting ultraviolet rays, the phosphors emit light and a predetermined image is displayed on the display panel. can be formed.

(Problems to be Solved by the Invention) According to the gas discharge display device having the conventional configuration described above, the display discharge area partitioned by the plurality of elongated dielectric layers 3a is divided into a pair of display discharge areas by the optical pattern 1. Since it is extremely difficult to narrow the formation pitch between a pair of adjacent display discharge regions t, it becomes impossible to display at the boundary W, and the 8 precision I
Not only is this a hindrance to increasing the display panel to 11 degrees, but it is also difficult to increase the aperture ratio of the display panel, and it is naturally impossible to increase the brightness of the display surface.

<Means for Solving the Problems> The present invention solves the above-mentioned problems, and has an mta configuration that allows for large-sized and g

In the gas discharge display device of the present invention, a front glass plate 21, which is a transparent insulating substrate, is opposed to a rear glass substrate 22, which is an insulating substrate, with a dielectric layer 23a interposed therebetween, thereby forming an area of 11i. , on the front surface substrate 21 are a long cathode busbar 24 mainly made of Ni formed by F7rJ film printing, vacuum deposition, sputtering, etc., and a pair of cathodes iM (first electric electrodes). ) 25.25 are disposed, while on the back glass substrate 22, a long l1iJ mainly consisting of a rim (gold) formed in a 71-lix shape by the same thin film forming means so as to be orthogonal to the cathode generatrix 24.24 is disposed. A display anode bus bar 26 and a display anode (second electrode) 27.27 are arranged. In addition, a light shielding film 31 is formed between a pair of cathodes 25 and 25 on the front glass 1.! plate 21 within the discharge area, and a dielectric layer 23C formed on this light shielding film 31 and The dielectric layer 23b formed on the rear glass substrate 22 is connected to the auxiliary anode (

A phosphor 29 is formed by covering with an insulating layer formed by vacuum evaporation or the like, and then applying a photoresist paste and attaching it by a method such as photo-etching. Incidentally, if the phosphor 29 does not contain a bottle, there is no need to provide an insulating layer.

A mixed gas mainly consisting of e-Xe is filled in the cells defined by the area for display II and the forehead in this manner.

The operation of the display device having the above configuration is such that the phosphor 29 present on the rear glass male plate 22 is caused to emit light by ultraviolet rays generated by the air 11i electricity between the display anode 27 and the negative 1fi 25, and the light is transmitted to the front glass substrate. 21 to radiate.

Then, as described above, the pilot discharge is sequentially transferred to each auxiliary anode 28 by a predetermined pulse, and in synchronization with the transfer timing of the pilot discharge, an image signal or the like is introduced to the display anode 27 in the discharge display area. By applying a pulse,
A predetermined image can be formed.

Therefore, by providing the auxiliary anode 28 between the dielectric layers 238 facing the discharge region, the discharge in the discharge region can be easily controlled, and the gas tIl lightning display '5A with a reliable self-scanning function is provided. times can be realized.
