ABSTRACT:
In a planar type display device, deterioration of the picture quality caused by distortion of laminated electrodes due to temperature rise in use is prevented by laminating the electrodes having such a structure that each electrode plate is free from expansion and contract by thermal expansion. Securing means spacers 23 thicker slightly than electrode plates are inserted in holes of the electrode plates 21a to 21e, securing means pin 24 is passed therethrough holding electrode plate spacers 22 therebetween, forming laminated electrode group 5. Since the respective electrode plates have slight gaps in a thickness direction and the electrode plates are free from expansion and contraction and do not distorted at the time of thermal expansion.
