ABSTRACT:
A plasma-addressed electro-optic display device comprising a layer of electro-optic material, data electrodes coupled to the electro-optic layer and adapted to receive data voltages for activating portions of the electro-optic layer, and a plurality of plasma channels extending generally transverse to the data electrodes for selectively switching on said electro-optic portions. The plasma channels each comprise spaced elongated cathode and anode plasma electrodes and an ionizable gas filling. To improve performance and increase the effective aperture and provide a stable discharge, the channels are configured with a substantially flat bottom surface portion and curved side wall surface portions on which the electrodes are deposited such that the spacing between the electrodes is increased and the electrode surfaces form an angle of the order of 90.degree.. Additional features include provision of black masking to screen out incident light that may depolarize, and a novel method of forming the electrodes using a single mask.
