Abstract
An electro-optical device has a plurality of electro-optical elements arranged in a matrix and optically activated selectively in response to voltage pulses applied thereto. Each electro-optical element is comprised of first and second electrode layers opposed to each other for selectively receiving thereacross a voltage pulse, and a third electrode layer adjacent to the first electrode layer and in opposed relation to the second electrode layer. A liquid crystal layer is interposed between the second and third electrode layers and optically activated when electrically charged through the third electrode layer. A non-linear-resistive layer is disposed between the first and third electrode layers and operative when the voltage pulse is applied across the first and second electrode layers to increase its electro-conductivity for electrically connecting the first electrode layer to the third electrode layer to thereby electrically charge the liquid crystal layer in response to the voltage pulse. The non-linear-resistive layer is comprised of non-stoichiometric silicon oxide or silicon nitride.
