ABSTRACT:
A plasma address liquid crystal display device is arranged such that an ineffective transparent electrode formed in an ineffective picture screen area of its liquid crystal cell is grounded or is applied with a drive voltage substantially same as that applied to a liquid crystal electrode formed in an effective picture screen area adjacent to the ineffective transparent electrode, whereby it is possible to avoid the generation of unstable electric field between the ineffective transparent electrode and the liquid crystal electrode.
