Abstract: The object of the present invention is to provide a touch panel member that is excellent in terms of suppression of visibility of a transparent electrode and has low total reflection for visible light, and a touch panel and a touch panel display device having the touch panel member. The touch panel member of the present invention comprises, in order, at least a transparent substrate, a transparent electrode, and a protective layer provided so as to cover the transparent electrode, the protective layer comprising three or more layers having different refractive indices, all of the different refractive index layers of the protective layer satisfying a specific expression, and the protective layer satisfying another specific expression.
