摘要： On a front substrate, a dielectric layer for accumulating the wall charge is formed, and inside the dielectric layer, a first electrode and a second electrode intersecting each other are formed with a predetermined pitch. The dielectric layer is not flat but is convex at the intersection of the first electrode and the second electrode, and the thickness in the direction of the discharge space from the second electrode at the intersection is larger than the thickness in the remaining area. Consequently, since the electric field distribution at the intersection is coarser than that at places apart from the intersection when discharge is sustained by causing an electric field distribution in the discharge space through the dielectric layer, discharge occurs not at the intersection but in four positions at places apart from the intersection, so that the luminous efficiency per discharge cell is improved.
摘要翻译：在前基板上形成用于积蓄壁电荷的电介质层，并且在电介质层内部以预定的间距形成彼此交叉的第一电极和第二电极。电介质层不是平坦的，而是在第一电极和第二电极的交叉点处是凸的，并且在交叉点处来自第二电极的放电空间方向上的厚度大于其余区域中的厚度。因此，由于在通过电介质层引起放电空间中的电场分布来维持放电时离交叉点的交点处的电场分布更粗糙，所以不在交叉点处发生放电，而是在四个位置除了交叉点，使得每个放电单元的发光效率提高。

摘要： A plasma display device performing display control by utilizing plasma discharge includes a panel having a plurality of address electrodes and a plurality of display electrodes disposed to intersect with the address electrodes, and a drive circuit performing address discharge drive for selectively producing a discharge in cells between the address electrodes and the display electrodes, and display discharge drive for applying to the display electrode a display drive pulse having a voltage increasing with such a gradient as to continuously produce a discharge current in the selected cell. In the display discharge drive performed after the address discharge drive, a display drive pulse with an increasing voltage of gentle gradient is applied to the display electrode, thereby producing faint discharges continuously in the selected cell during the increase of the voltage applied to the display electrode. Display luminance is controlled by the above ramp-wave discharge. In such the ramp-wave discharge, differently from the conventional strong discharge, faint discharges are produced a plurality of times while the display drive pulse is being applied, enabling improvement on the discharge efficiency, and reduction of power consumption.
