Abstract

PURPOSE:To reduce the arranging pitch of discharge sustaining electrodes and easily provide the high resolution of a face discharge-type gas discharge panel by making the discharge sustaining electrodes with paired comb tooth sections in an electrode structure with individual comb tooth sections engaged with each other. CONSTITUTION:Discharge sustaining electrodes 32, 33 with adjacent and paired comb tooth sections 32a, 33a are arranged face to face on a lower glass substrate 31 functioning as an electrode support substrate so that individual comb tooth sections 32a, 33a are engaged with each other. Discharge sustaining discharge cells Sc are constituted between the comb tooth section 32a of one discharge sustaining electrode 32 and the portion with no comb tooth section of the other discharge sustaining electrode 33, for example. Writing electrodes 35 are arranged on them through a thick dielectric layer 34 made of low-melting point glass in a direction crossing individual discharge sustaining electrodes 32, 33, and writing discharge cells Wc are constituted corresponding to each intersection with either one of the discharge sustaining electrodes 32, 33 respectively. In addition, said writing electrodes 35 are coated with a surface layer 36.

is installed.

For example, at each intersection between one of the discharge sustaining electrodes 2 and the write electrode 5, a discharge cell We for writing is formed by corresponding 1-. Furthermore, the write electrode 5 is coated with a dielectric layer 6 made of alumina (A1203) or the like, and its surface is covered with a surface layer 7 of MgO.

An upper glass substrate 9 for a cover is sealed with a predetermined gas filling gap 8 therebetween, facing the electrode substrate constructed in this way, and a predetermined discharge gas is filled in the gap 8. The display panel is complete. By applying a predetermined voltage between the selected discharge sustaining electrode 2 and write electrode 5, the discharge 1 generated in the write cell Wc near the intersection of these electrodes is transferred to the adjacent pair to which the predetermined sustaining voltage is applied. Discharge cell Sc for sustaining discharge configured between sustaining electrodes 2 and 3
write cell W so as to maintain free wL in the form of inheritance.
A structure is adopted in which the discharge sustaining cell SC'jk is functionally separated from the discharge sustaining cell Egc and the discharge sustaining cell SC'jk is constructed by a pair of adjacent electrodes that do not intersect, thereby preventing current concentration from occurring in the vicinity of the adjacent electrode pair during discharge. ing.

However, in the surface discharge type gas discharge panel having such a configuration, the comb-teeth protrusions 2a and 2b of the adjacent discharge sustaining electrodes 2 and 3 are close to each other to form the discharge cell Sc for sustaining the discharge. Because of this structure, the distance between the pair of discharge sustaining electrodes 2 and 3 cannot be easily narrowed, making it difficult to increase the resolution of the panel.

(b) Purpose of the Invention In view of the above-mentioned conventional situation, an object of the present invention is to provide a novel surface discharge type gas discharge panel that can perform high resolution display without impairing the function of the spring latch. It is something that can be done.

(e) Structure and object of the invention According to the present invention, a pair of comb-shaped electric discharges is provided adjacently to each other on one of a pair of substrates facing each other with a discharge space in between. It has write electrodes arranged in a direction intersecting the discharge sustaining electrodes through an electrode and an insulating film, and when the discharge occurs near the intersection of one of the pair of discharge sustaining electrodes and the writing electrode. In a panel configuration in which discharge is sustained between adjacent pairs of discharge sustaining electrodes, the comb teeth of each of the pairs of discharge sustaining electrodes are arranged adjacently so as to mesh with each other, and each discharge sustaining N
This is achieved by providing a gas discharge spring /l/ characterized in that the discharge is maintained between the comb-teeth part of the pole and the adjacent discharge-sustaining type (the part between the comb-teeth of the station). .

For example, chromium (Or) in a thin film.

A three-layer electrode structure of copper (Cu) and chromium (Or) is arranged facing each other. For example, a discharge cell/I/SC for sustaining a discharge is formed between the comb-toothed portion 82a of one of the discharge sustaining electrodes 82 and the adjacent portion without the comb-toothed portion of the other discharge sustaining electrode 33. Thereon, for example, a thin film of chromium (Or) is formed in a direction intersecting each of the discharge sustaining electrodes 82, 33 via a thick dielectric layer 34 made of low-melting glass mainly containing lead oxide (PbO).
