Abstract
A transparent conductive film 1 includes, in this order, a transparent substrate 2, a first optical adjustment layer 4, an inorganic layer 5, and a transparent conductive layer 6. The first optical adjustment layer 4 has refractive index nC lower than refractive index nA of the transparent substrate 2, and thickness TC of 10 nm or more and 35 nm or less. The inorganic layer 5 has refractive index nD that is lower than the absolute value |nC×1.13| of a value obtained by multiplying the refractive index nC of the first optical adjustment layer 4 by 1.13.
Claims6
A transparent conductive film comprising, in this order, a transparent substrate, a first optical adjustment layer, an inorganic layer, and a transparent conductive layer,
- wherein the first optical adjustment layer has a refractive index lower than the refractive index of the transparent substrate and has a thickness of 10 nm or more and 35 nm or less,
- a ratio of a thickness of the inorganic layer to a thickness of the first optical adjustment layer is 0.350 or less,
- a ratio of a thickness of transparent conductive layer to the thickness of the inorganic layer is 5 or more, and
- the inorganic layer has a refractive index, the refractive index being lower than or the same as the absolute value of a value obtained by multiplying the refractive index of the first optical adjustment layer by 1.13.
