Estimating the term…
A thin conductive film which excels in film strength, weather resistance, transparency, and electric field shielding effect is formed on a glass substrate at a low temperature as a multilayer film which is formed of an ITO-dispersed silicate layer and an overcoat silicate layer, or at least two layers of an ITO dispersed silicate and a high-conductivity oxide-dispersed silicate, and a topmost layer of an overcoat silicate. The ITO dispersed silicate layer includes ultra fine particles of indium tin oxide and a silicate-based glass matrix, and the high-conductivity oxide-dispersed silicate layer consists of includes ultra fine particles selected from the group of ruthenium dioxide, rhenium trioxide, iridium dioxide, rhodium dioxide and irridium-based pyrochlore and a silicate-based glass matrix.
A combination of a glass substrate and a transparent conductive film for electric field shielding formed on said glass substrate, said transparent conductive film comprising a first layer of an ITO dispersed silicate containing between 0.1 and 25% by weight of fine particles of a high-conductivity oxide selected from the group consisting of ruthenium oxide and ruthenium pyrochlore, and a second layer of transparent silicate glass, said first layer being located between said glass substrate and said second layer.
A combination of a glass substrate and a transparent conductive film for electric field shielding on said glass substrate, said transparent conductive film comprising three layers formed over said glass substrate, wherein a first layer consists of an ITO dispersed silicate layer containing between 0.1 and 25% by weight of fine particles of a high-conductivity oxide selected from the group consisting of ruthenium oxide and ruthenium pyrochlore, a second layer is a high-conductivity oxide-dispersed silicate layer, and a third layer is an outermost layer.
