Abstract
The transparent conductive laminate of the invention is a laminate comprising a film made of a polymer with a photoelastic constant of no greater than 70×10Pa, a light-scattering layer with a haze value in the range of 0.2-1.4% formed on one side thereof, and a transparent conductive layer formed on the other side thereof, wherein the laminate exhibits an overall retardation of λ/4. By using the laminate it is possible to provide touch panels with reduced light reflection, no coloration, excellent visibility and high reliability for outdoor use, as well as touch panel-equipped liquid crystal displays employing them.
