摘要： PURPOSE:To easily ionize ionizable gas contained inside a groove, to improve productivity and to obtain a wide view angle even when the groove filled with the gas is comparatively shallow by making the width of a reference electrode wider than that of a data strobe electrode. CONSTITUTION:Electrodes 112a of a groove 62a are provided with a widened width 130a, and those electrodes are connected to a common reference potential fixed to a ground potential. Electrodes 114a of the grooves 62a are connected to respectively different amplifiers 74 of a data strobe circuit 76. The respective grooves 62a are filled with the ionizable gas. In order to designate the address of a display element 56 which position is matched with the groove 62a, the gas inside the groove 62a is operated as an anode. The gas is selectively ionized by arrangement provided with the reference electrodes 112a and the row electrodes 114a operated as the anodes. The widened width 130a of the reference electrodes 112a applies a comparatively large conductive plane area to the respective grooves 62a and facilitates the ionizing of gas contained in the grooves 62a.

摘要： PURPOSE:To solve the problem of the bending by which constituting elements to be supported are affected by forming island-shaped parts in such a manner that the front surfaces of these parts have a relatively large front area in order to support electro-optical material layers and the constituting elements, such as second substrate. CONSTITUTION:The island-shaped parts 60 projecting from the first substrate 64 respectively have the flat and relatively large front surfaces formed with conductive layers 130 and are arranged in approximately parallel island-shaped part rows 62. Net-like grooves 110 have slender grooves 124a arranged between the adjacent island-shaped part rows and branched grooves 124b extending between the individual island-shaped parts within the respective rows. The superposed parts of the column electrodes 58 and island-shaped part rows formed on the second substrate 66 form data elements. The electro-optical material layers 68 are interposed between the first and second substrates and ionizable gases are housed between the layers 68 and the first substrates.

摘要： PURPOSE:To lessen the influence of the crosstalks of an electrooptical address assigning structural body. CONSTITUTION:A plasma address liquid crystal display device 10 is lessened in sensitivity with the crosstalks by using a liquid crystal material 18 having low DELTAepsilon, epsilon¦ and DELTAn, by which the resistance to the harmful electrochemical effect of DC bias is improved. The liquid crystal layer having the low DELTAepsilon, epsilon¦ and DELTAn is low in capacity and is increased in threshold voltage, and a saturation voltage is decreased, the sensitivity with the crosstalks is lowered and the operating voltage is dropped.

摘要： PURPOSE:To provide the electrode structural body in such a manner that the plural electrodes formed on a substrate are respectively commonly usable in adjacent grooves, the number of the electrodes to be formed is halved, the width of the respective electrodes is increased and the yield of the electrode structural body is improved. CONSTITUTION:This electrode structural body for a plasma address assigning device assigns addresses by selectively ionizing the ionizable gases filled within the plural grooves. The plural electrodes 104, 106, 108, 110, 112 are formed on the insulating substrate 102 and insulating wall parts 116, 118, 120, 122, 124 are formed on the respective electrodes. A dielectric cover 126 is supported and the plural grooves are formed. The respective electrodes are exposed within a pair of the adjacent grooves.

摘要： PURPOSE:To form the shape of a photosensitive member structural body repeatedly with accuracy. CONSTITUTION:A desensitization layer 18 is formed on the second principal face 14 of a photosensitive member 10 by applying a desensitizer. Next, light is selectively emitted to a first principal face 12 on the opposite side of the second principal face 14 using a masking agent. After that, a groove 32 is formed by etching using a phenomenon that the exposed area of the photosensitive member 10 subjected to light emission is etched at faster speed than the desensitized layer 18 whose etching speed is adequately low. Thus it is possible to form a bottom 38 having the same thickness as the desensitized layer 18 prepared previously in each groove 32.

摘要： PURPOSE:To provide an electrooptic address assigning device with decreased crosstalk effect by incorporating a liquid crystal material showing such frequency reactivity that the dielectric anisotropy for the signal frequency higher than the critical frequency is almost zero. CONSTITUTION:The line electrode 20 is formed on the principal plane of a non-conductive light transmitting substrate 24, and a groove 22 is formed on the principal plane of the second nonconductive light transmitting substrate 26. A layer 28 consisting of a frequency-reactive electrooptical material such as two-frequency nematic liquid crystal is interposed between a first nonconductive light transmitting substrate 24 and a second nonconductive light transmitting substrate 26. In this constitution, it is preferable that the dielectric anisotropy DELTAepsilon of the frequency-reactive liquid crystal material in the layer 28 is rather small for the signal frequencies higher than the specific frequency fth, and more preferably, almost zero. Thereby, the frequency-reactive liquid crystal material does not substantially react with signals having higher frequencies than the critical frequency. This device includes a data driver which sends reversed data signal in a first period and non-reversed data signal in the second period to each picture element.
