[0051] In the same manner as the first embodiment, as shown in FIG. 3, an apparatus according to this second embodiment includes a liquid crystal cell 101 and a plasma cell 102 with a thin glass plate 103 interposed therebetween. First, a plurality of lower layers 114 are formed on a glass substrate 108 at equal intervals, and then a plurality of discharge electrodes 109 are formed on these lower layers 114 . Next, insulating ribs 110 are printed on these discharge electrodes 109 so that the sinter 111 is spread around the insulating ribs 10 . A thin glass plate 103 is then placed on the upper ends of the insulating ribs 109 to form a plurality of discharge regions 112 . Then, a liquid crystal layer 107 is provided between the thin glass sheet 103 and the plurality of display electrodes 105 formed on the thin glass sheet 103 so as to be perpendicular to the plurality of discharge electrodes 109 . In this embodiment, insulating ribs are also provided on all discharge electrode...

Abstract

A plasma addressing display device includes a first substrate with a plurality of first electrodes arranged alternately and side by side on the main surface, and a plurality of electrodes perpendicular to the first electrodes and arranged side by side alternately and facing the first electrodes. The second substrate of the second electrode, an insulating sheet interposed between the first and second substrates, an electro-optical substance for maintaining a space between the insulating sheet and the first substrate, and the A lower layer is formed between the second substrate and the second electrode, thereby suppressing the sinking of the glass substrate on the side wall of the plasma box and controlling the substrate discharge inside the plasma box.

Description

technical field [0001] The invention relates to a plasma-addressed display device having a flat-panel structure of a superimposed display cell and a plasma cell. Background technique [0002] A plasma addressing display device utilizing a plasma cell as an addressing display cell has been proposed, as in Japanese Patent Laid-Open Publication No. Hei.4-265931 (authorized date: September 22, 1992) This device is presented in . As shown in FIG. 5, the plasma-addressed display device has a flat panel structure including a display cell 501 and a plasma cell 502 interposing a thin glass sheet 503 composed of an insulating sheet. The plasma cell 502 consists of a lower substrate 504 sintered to a thin glass sheet 503, and ionized gas is injected into the space between the glass sheet 503 and the lower substrate 504. Since the discharge electrode 505 can be printed and baked on the flat plate 509 using a technique such as screen printing, it is possible to produce a discharge elec...
