LARGE SCALE HIGH RESOLUTION LIQUID CRYSTAL DISPLAY AND METHOD FOR PRODUCTION THEREOF ABSTRACT OF THE DISCLOSURE A matrix addressable liquid crystal display includes a thin film circuit supported on a sub- strate having a plurality of parallel bit lines. A plurality of individual pixel circuits each include a two terminal bi-directional gate device which is formed from at least one thin film layer with one gate device terminal connected with the associated bit line. A terminal plate is con- nected in circuit with the other terminal of the gate device. A transparent cover plate is spaced above the thin film circuit with a transparent conductor structure on the underside of the cover plate. The space beneath the cover plate is filled with a liquid crystal display material to form indi- vidual display pixel circuits at the terminal plates. A plurality of parallel word lines are arranged orthogonally to, and insulated from, the bit lines. The word lines are connected in cir- cuit with the individual display pixel circuits at the respective cross-overs with the bit lines. The pixel circuits are each operable to change the state of the associated portion of the liquid crystal display material in response to the con- current application of voltage pulses of opposite polarities to the associated word and bit lines.
