Title: Plasma display device
Inventor: MAKINO MITSUYOSHI
IPC: H01J11/26
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To improve high definition, while securing emission luminance. SOLUTION: This plasma display device is provided with a front surface substrate and a back surface substrate which are arranged facing each other, plural pairs (electrode pairs) of scanning electrodes and common electrodes which extend on the inner surface of the front surface substrate in approximately the same direction at a distance (a surface discharge distance), and a plurality of data electrodes extending on the inner surface of the back surface substrate at a distance, so as to be approximately perpendicular to the scanning electrodes and the common electrodes, and discharge gas is filled between the substrates.  The product of the surface discharge distance by discharge gas pressure is set so as to be lower than the Paschen minimum, less likely the discharge is not generated, the smaller the distance is between the electrodes, and the electrode pairs are arranged thickly to realize high definition. Since the distance between a scanning electrode 12 and a common electrode 13 of different electrode pairs, namely, the sum of the non-discharge distance NDG and the width W of either the scanning electrode 12 or the common electrode 13 is smaller than a surface discharge distance DG, errors in discharging in paths B between mutually adjacent electrode pairs can be prevented.
