Abstract
Abstract An electro-optic display device in which a conductive paste is disposed between opposed electrodes is characterized in that said conductive paste contains silane coupling agents. A process for making an electro-optic display device in which a conductive paste is disposed between opposed electrodes is characterized in that said conductive paste is applied onto films which are formed by applying a silane coupling agent onto at least one of the electrodes.

Claim 1
Independent Claim
84 words
An electroconductive adhesive for bonding a pair of electrodes formed of the material selected from the group consisting of metals, indium oxide and tin oxide comprising: (a) 0.05-10% by weight of an organic silicon monomer having a reactive silicon radical and a reactive organic radical; (b) at least one electroconductive powder selected from the group consisting of carbon, silver, gold, copper and aluminum powder in an amount sufficient to impart electroconductivity; and (c) an epoxy resin adhesive in an amount sufficient to impart adhesiveness.
Claim 2
Dependent Claim
84 words
An electroconductive adhesive for bonding a pair of electrodes formed of the material selected from the group consisting of metals, indium oxide and tin oxide comprising: (a) 0.05-10% by weight of an organic silicon monomer having a reactive silicon radical and a reactive organic radical; (b) at least one electroconductive powder selected from the group consisting of carbon, silver, gold, copper and aluminum powder in an amount sufficient to impart electroconductivity; and (c) an epoxy resin adhesive in an amount sufficient to impart adhesiveness.
Claim 3
