Bidirectional nonlinear resistor, active matrix liquid crystal panel using bidirectional nonlinear resistor, and method for production thereof

A method for preparation of an electro-optical cell for an electro-optical display device comprising:

• a) selectively depositing a first conductive wire on a first transparent substrate;
• b) forming a highly insulating electrolytic polymer film on at least a portion of the first conductive wire by electrolytic polymerization of an electrolytic solution;
• c) forming a first transparent electrode on the entire surface of the first substrate;
• d) shaping the first transparent electrode into a designated pattern to form conductor-insulator-conductor nonlinear resistors used as switching elements for driving an electro-optical display device;
• and
• e) attaching a second transparent substrate having a second transparent electrode selectively deposited thereon for cooperating with the first transparent electrode on the first transparent substrate with a space therebetween.

A method for preparation of an active matrix substrate comprising:

• a) forming a first electrode of a designated pattern on a first transparent substrate;
• b) depositing a highly insulating electrolytic polymer film on the electrode by electrolytic polymerization of an electrolytic solution;
• c) selectively forming a plurality of second conductors in the designated pattern on the insulting polymer film to form a conductor-insulator-conductor structure which functions as a nonlinear resistor;
• and
• d) selectively depositing a picture element on or adjacent to each second conductor.
