1. A matrix multiplexed display comprising a pair of plates, at least one of the plates being transparent, the plates having sealed therebetween a layer of liquid characterized by electric field dependent optical transmissivity, a first plurality of electrodes on an inside surface of one plate and a second plurality of electrodes on an inside surface of the other plate, the display having a plurality of picture elements, each element defined by a pair of opposed electrodes on the inside surfaces of respective plates, means for applying a voltage between the opposed electrodes of each element, each picture element being series connected to a respective switch comprising a thin insulating film flanked by thin film conducting layers, the insulating film characterized by a gross change in resistivity at a predetermined voltage thereacross, the switches formed on the inside surface of at least one of the plates, each switch having a capacitance substantially less than the capacitance of its series connected picture element.
