PURPOSE:To prevent any oxidation of the electrodes which might develop through exposed parts of the electrodes during a panel manufacturing process, and prevent any accidental mis-discharge, which might be induced by the maldistribution of unusual charges, by providing cracks used for exhausting unusual charges developed in dielectric layers. CONSTITUTION:The peripheries of an outermost-end electrodes 7 and y2n are made steep. Dielectric layers have multi-layered structures which are formed, respectively, by layering the first Al2O3 deposition layers 3a and 5a, borosilicate glass deposition layers 3b and 5b and the second Al2O3 deposition layers 3c and 5c, in that order. Parts of the second dejposition layers 3c and 5c corresponding to the peripheral parts of the electrodes 7 and y2n are provided with cracks 10. As a result, since unusual charges accumulated in surfaces of the dielectric layers located at both ends of a shift channel can be leaked through the cracks 7 into the writing electrode 7, the generation of accidental mis-discharge can be avoided. Here, since the cracks 10 are provided only in the second Al2O3 deposition layers 3b and 5b, the electrodes 7 and y2n are completely shielded from the atmosphere. As a result, any oxidation of the electrodes which might be caused by thermal treatment carried out during the panel manufacturing process can be prevented.
