PURPOSE:To prevent the storage of abnormal charge by employing a porous dielectric material layer for covering the electrode which constructs the discharge cell at one end of a shift channel and leaking the abnormal charge through the holes in said porous layer. CONSTITUTION:Glass substrates 2 and 5 formed with two groups of (Y) side shift electrodes y1i , y2i and (X) side shift electrodes X1j, X2j, dielectric material layers 3 and 6 and the surface layers of MgO 4 and 7 are faced each other to form a shift channel 8 in the gas discharge space 1. A writing electrode 9 is provided at the right end of the shift channel 8 thus to form a writing discharge cell (W). Then the porous sections 11 extending from the surface layer to the end section of the electrode are provided on the dielectric material layer 3 and 7 corresponding to the outermost electrode y2n and the writing electrode 9. The unnecessary wall charge on the dielectric material layer is leaked through said porous section to the electrodes y2n and 9. Consequently the abnormal storage of charge can be prevented. |
