Abstract
Abstract A bidirectional nonlinear resistor for use as a nonlinear active element having a highly insulating organic film formed on a first conductor by polymerizing an electrolytic solution containing a supporting electrolyte and a soluble organic compound, and a conductor identical or not identical in kind with the first conductor formed on the organic film is provided. An active matrix substrate including a plurality of the bidirectional nonlinear resistor elements may be used to have a liquid crystal display panel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
148 words
A method for preparation of an active matrix substrate comprising: (a) forming a first electrode in a designated pattern of parallel rows on a first transparent substrate; (b) depositing a transparent insulating film on at least the entire exposed surface of the first electrode; (c) forming a contact hole in the insulating film to the electrode; (d) depositing an electrolytic polymer film through the contact hole on the electrode by electrolytic polymerization; (e) depositing picture elements on a portion of the first transparent substrate; and (f) depositing a conductor in a designated pattern on at least a portion of the electrolytic polymer film with at least a portion thereof opposed to a portion of the first electrode with the electrolytic polymer film therebetween to form a conductor-insulator-conductor structure which functions as a nonlinear resistor, and with at least a portion of the conductor connected to the picture elements.
Claim 2
Independent Claim
148 words
A method for preparation of an active matrix substrate comprising: (a) forming a first electrode in a designated pattern of parallel rows on a first transparent substrate; (b) depositing a transparent insulating film on at least the entire exposed surface of the first electrode; (c) forming a contact hole in the insulating film to the electrode; (d) depositing an electrolytic polymer film through the contact hole on the electrode by electrolytic polymerization; (e) depositing picture elements on a portion of the first transparent substrate; and (f) depositing a conductor in a designated pattern on at least a portion of the electrolytic polymer film with at least a portion thereof opposed to a portion of the first electrode with the electrolytic polymer film therebetween to form a conductor-insulator-conductor structure which functions as a nonlinear resistor, and with at least a portion of the conductor connected to the picture elements.
Claim 3
Dependent Claim
18 words

Claim 6
Independent Claim
172 words
A method for preparation of an active matrix substrate comprising: (a) forming a first electrode in a designated pattern on a first transparent substrate; (b) depositing an electrolytic polymer film containing a doping agent on the electrode by electrolytic polymerization; (c) depositing a transparent insulating film on at least a portion of the electrolytic polymer film such that at least a portion of the transparent insulating film is opposed to either a portion of the first transparent substrate or at least a portion of the first electrode with the electrolytic polymer film therebetween; (d) forming a contact hole through a designated part of the insulating film to expose a portion of the electrolytic polymer film; (e) depriving the doping agent contained in the electrolytic polymer film through the contact hole thereby forming a highly insulating electrolytic polymer film; (f) depositing a conductive material in a designated pattern thereby forming a conductor-insulator-conductor structure which functions as a nonlinear resistor; and (g) selectively depositing a picture element on or adjacent to the transparent conductor.
