ABSTRACT:
An electrode pattern for a liquid crystal display comprises an electrode pattern having at least one dummy scan and/or signal electrode at a region other than a display pattern having true scan electrodes and true signal electrodes for displaying a specific display indicia. A circuit is provided for applying an OFF voltage to the dummy scan and/or signal electrode, the OFF voltage making this dummy electrode erased. The dummy electrodes are positioned and spaced in a manner identical to the true electrodes to simulate the overall appearance of the true electrode display region.
