Abstract: PROBLEM TO BE SOLVED: To eliminate the need for an offset voltage to be applied to a drive voltage by eliminating a battery effect leading to the asymmetry of liquid crystal response, to ensure a high reliability even in a long-term drive, and to enable easy manufacture without complicating the manufacturing process. SOLUTION: A conductive thin film 43 made of the same material as a confronting transparent electrode is formed, via an insulating thin film 45, on the surface of a pixel electrode 42A confronting with the transparent electrode. By providing the conductive thin film 43, the battery effect between the confronting electrodes. Thus, the asymmetry of liquid crystal response is eliminated, and the offset voltage conventionally required for the drive voltage can be dispensed with. As a result, the reliability in the long-term drive can be enhanced. Also, since the conductive thin film 43 is coated via the insulating thin film 45, the electric current between the adjacent pixel electrodes 42A is prohibited. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To accurately polish the top parts of respective diaphragms formed in a plasma cell without damaging or collapsing the diaphragms. SOLUTION: The plasma address display device consists of a plasma cell provided with discharge channels successively arrayed along a scanning direction, signal electrodes joined with the plasma cell and successively arrayed in the direction rectangular to the scanning direction and a display cell provided with an electro-optical substance layer brought into contact with the signal electrodes. The plasma cell has a substrate 8 jointed with a display cell through a prescribed gap, discharge electrodes 9 formed on the substrate 8 along respective discharge channels and diaphragms formed on the substrate 8 so as to mutually partition respective channels 9. In order to prepare the plasma cell, discharge electrodes 9 are formed on the substrate 8 at first. Then an insulating layer 10a is formed on the whole surface of the substrate 8 so as to be superposed to the electrodes 9 to obtaine prescribed thickness or more. Then the surface 10b of the layer 10a is polished up to prescribed thickness to flaten the surface 10b. Then, the layer 10a is selectively ground by sand blast to work diaphragms. Finally a dielectric sheet is fitted so as to be brought into contact with the top parts of respective diaphragms and a display cell is formed on the surface of the sheet.

Abstract: PURPOSE: To prevent the crack of a dielectric sheet and the unequal display according to the slack of this dielectric sheet by setting the spacing distance between struts or between the partitions adjacent to these struts larger than the spacing distance between the partitions disposed in effective pixel regions. CONSTITUTION: The spacing distance between the partitionsions 5 in the effective pixel regions is set at an ordinary spacing distance. The struts 37 of the same structure and the same direction as those of the partitions 5 are disposed in non-effective regions and the spacing distance (b) between the struts 37 is set larger than the spacing distance (a) of partitions. The dielectric sheet 4 does not sag downward as the partitions 5 are formed at a fine pitch in the effective pixel regions even if the sheet 4 has the slack at the time of bringing the sheet 4 into tight contact with barrier ribs 33 by vacuum suction from a discharge pipe P. On the other hand, the pitch between the struts 37 in the non-effective regions is wide and, therefore, the sheet 4 eventually sags downward between the struts 37 and the slack of the sheet 4 in the non-effective regions is absorbed and the sag is not produced in the effective pixel regions. The unequal gap of liquid crystals is thus lessened.

Abstract: PURPOSE:To stably perform a process of polishing a partition formed in a plasma cell of a plasma address liquid crystal display device. CONSTITUTION:A plasma address liquid crystal display device, in which a plasma call and a liquid crystal cell are superposed on each other through an intermediate sheet, is manufactured as follows. First in a substrate 2 previously formed a plasma electrode 1, stripe-shaped partitions 3 are formed to be printed. Next, a part between the stripe-shaped partitions 3 is changed with a temporary reinforcing material 4, to bury the periphery of the individual partition. Successively in a buried condition, a top part of each partition 3 is polished and flattened. Thereafter, the temporary reinforcing material 4 is removed to expose a plasma electrode 1. Finally coming into contact with the flattened top part of each partition 3, the intermediate sheet is connected to assemble the plasma cell.

Abstract: PROBLEM TO BE SOLVED: To prolong the lifetime by decreasing the discharge current of a plasma cell. SOLUTION: This plasma address display device basically comprises a flat panel 0 wherein a display cell provided with column-formed signal electrodes Y and a plasma cell provided with row-formed discharge channels are laminated and pixel are arranged at the intersections of each signal electrode Y and each discharge channel, a scanning circuit 22 for selecting the pixels for every row by sequentially discharging the row-formed discharge channels at every prescribed cycle, and a signal circuit 21 for sequentially supplying image signals to column-formed signal electrode Y synchronizing with the prescribed cycle and writing the image signals in the pixels of the selected rows. The scanning circuit 22 is enabled to allocate a discharge period longer than the prescribed cycle to each discharge channel by allowing each discharge channel to be discharged while overlapping a discharge period allocated to a discharge channel of the preceding row on a discharge period allocated to a discharge channel of at least the following row and thus shifting each discharge channel in time. Thus, the lifetime is prolonged by decreasing the discharge current of the plasma cell.
