ABSTRACT:
There are disclosed liquid crystal displays each having at least one pixel element formed on an insulative substrate including at least two conductive electrodes and liquid crystal display material disposed between the electrodes. The pixel elements further include at least a pair of isolation devices formed from a deposited semiconductor material which facilitates selective excitation of of the pixel elements and applied potential reversal across the electrodes during alternate display frames. The isolation devices can include a plurality of series connected diodes. The isolation devices can be formed as diode rings. A method of making the displays is also disclosed.
