Abstract

Abstract A liquid crystal display device comprises two opposed substrates (1,6), a layer (5) of liquid crystal material between the substrates, row electrodes (4) formed on the inner surface of the substrate (1) and column electrodes (7) formed on the inner surface of the other substrate (6) and pixel electrodes (2) and non-linear resistance elements formed on the substrate (1) and connected in series with one another. Each non-linear resistance element consists of a first conductor comprising a row electrode, second conductor comprising the first conductor and a pixel electrode, and amorphous material (3) consisting principally of silicon and formed between the first and second conductors.

Claim 1
Independent Claim 137 words
A liquid crystal display device comprising: two opposed substrates (1,6; 60,61;80,81); a layer (5; 62;82) of liquid crystal material between said substrates; a plurality of row electrodes (4; 63;83,85) formed on the inner surface of one of said substrates (1; 60;80); a plurality of column electrodes - (7; 66;86) on the inner surface of the other of said substrates (6; 61;81); and a plurality of pixel electrodes (2; 65;87) and non-linear resistance elements formed on at least one of said substrates (1; 60;80) and connected in series with one another; characterised in that each said non-linear resistance element consists of a first conductor comprising a row or column electrode, a second conductor comprising said first conductor and a pixel electrode and amorphous material (3; 64;84) consisting principally of silicon and formed between said first and second conductors.
Claim 2
Dependent Claim 137 words
A liquid crystal display device comprising: two opposed substrates (1,6; 60,61;80,81); a layer (5; 62;82) of liquid crystal material between said substrates; a plurality of row electrodes (4; 63;83,85) formed on the inner surface of one of said substrates (1; 60;80); a plurality of column electrodes - (7; 66;86) on the inner surface of the other of said substrates (6; 61;81); and a plurality of pixel electrodes (2; 65;87) and non-linear resistance elements formed on at least one of said substrates (1; 60;80) and connected in series with one another; characterised in that each said non-linear resistance element consists of a first conductor comprising a row or column electrode, a second conductor comprising said first conductor and a pixel electrode and amorphous material (3; 64;84) consisting principally of silicon and formed between said first and second conductors.
Claim 3
Dependent Claim 33 words
A liquid crystal display device as claimed in claim 1 characterised in that said amorphous material is silicon dioxide, silicon nitride or silicon oxide-nitride having a silicon content greater than the stoichiometric ratio.
Claim 4
Dependent Claim 20 words
A liquid crystal display device as claimed in claim 1 or 2 characterised in that said amorphous material includes hydrogen.
Claim 5
Dependent Claim 21 words
