摘要： PROBLEM TO BE SOLVED: To provide a display device permitting to achieve a switching characteristic of a two-terminal non-linear resistance element required for driving a liquid crystal with a wide operation range such as high-polymer distributed type liquid crystal, etc., by using zinc sulfide for a non-linear resistance layer of the two-terminal non-linear resistance element used as an active element. SOLUTION: A two-terminal non-linear resistance element 20 is composed of a lower electrode 13 electrically connected with a scanning electrode 12, a non-linear resistance layer 14 consisting of a material containing zinc sulfide as the main component, an insulation film 15, and an upper electrode 16 serving for a picture element electrode as well, which are sequentially laminated on a glass substrate 11. The non-linear resistance layer 14 is partly in contact with the upper electrode 16 via a contact hole 15a formed in the insulation layer 15, and is also heat-treated. Thus, it is possible to reduce an off-current value of the two-terminal non-linear resistance element 20 and also improve a current-voltage characteristic in steepness.

摘要： PURPOSE: To improve the steepness of the I-V characteristic of a nonlinear element. CONSTITUTION: A nonlinear resistance layer consisting essentially of zinc sulfide is formed by a sputtering method using an inert gas and gaseous oxygen as a sputtering gas, by which the nonlinear element consisting of a first electrode- nonlinear resistance layer-second electrode is produced. The steepness of the I-V characteristic 11 of the nonlinear element is made higher than the steepness of the I-V characteristic 12 of the nonlinear element in the case only the inert gas is used as the sputtering gas.

摘要： 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.

摘要： PURPOSE: To provide a display device having nonlinear elements which have continuous I-V characteristics and large nonlinear characteristics and are stable to a change with lapse of time and temp. change. CONSTITUTION: The nonlinear resistance layers 24 of the nonlinear elements successively laminated with first electrodes 22a, nonlinear resistance layers 24 and second electrodes 25a in this order are polycrystals which consist essentially of zinc sulfide and in which the crystal structure of the zinc sulfide includes a zincblende type structure. The nonlinear elements have the continuous I-V characteristics and large nonlinear characteristics and are stable to the change with lapse of time and temp. change. Since the crystal state is columnar, the effective passage of current to electric fields from outside is possible.
