Abstract
Official abstract text for this publication.
The present invention relates to a transparent conductive film which is excellent in dotting property under a heavy load and excellent in bending resistance. Provided is a transparent conductive film, comprising a flexible transparent base; and a transparent conductive layer formed on the flexible transparent base and including a crystalline indium/tin composite oxide, wherein a compressive residual stress of the transparent conductive layer is 0.4 to 2 GPa.
First claim
Opening claim text (preview).
The invention claimed is: 1. A transparent conductive film, comprising a flexible transparent base; and a transparent conductive layer formed on the flexible transparent base and including a crystalline indium/tin composite oxide, wherein a compressive residual stress of the transparent conductive layer is 0.7 to 2 GPa, wherein the transparent conductive layer is formed by a sputtering method, wherein the transparent conductive layer is crystallized by heating, and a dimensional change in at least one direction in a plane of the layer with respect to a dimension before crystallization is −0.3% to −1.5%, the flexible transparent base comprises a transparent substrate film and an undercoat layer, and the undercoat layer comprises an organic substance or a mixture of an inorganic substance and an organic substance. 2. The transparent conductive film according to claim 1 , wherein the content of crystals having a maximum grain size of 300 nm or less is 95% by area or more. 3. The transparent conductive film according to claim 1 , wherein the content of crystals having a maximum grain size of 200 nm or less is more than 50% by area. 4. The transparent conductive film according to claim 1 , wherein the content of crystals having a maximum grain size of 100 nm or less is more than 5% by area, and the maximum grain size of remaining crystals falls within a distribution range of more than 100 nm and 200 nm or less. 5. The transparent conductive film according to claim 1 , wherein the thickness of the transparent conductive layer is 10 to 100 nm.
