TRANSPARENTES TOUCH PANEL UND FLÜSSIGKRISTALLDISPLAY MIT EINEM TRANSPARENTEN TOUCH PANEL

摘要

A transparent touch panel (8) of the present invention comprises a pair of transparent conductive substrates (3, 4) and a retardation film (3). A transparent conductive film (6) is formed on at least one surface of each of these transparent conductive substrates (3, 4) and these transparent conductive substrates (3, 4) are arranged such that the transparent conductive films formed thereon are allowed to face each other. By depressing the transparent conductive substrate (3) on the upper side, these transparent conductive substrates are brought into mutual contact so as to perform the position detection. The retardation film (3) is made of an amorphous plastic material, meets the relationship nz ny and has a retardation R(0), which is represented by (nx - ny) x d, falling within a range of between 90 nm and 200 nm, wherein d represents the thickness of the film, nx represents the maximum refractive index within the plane of the retardation film, ny represents the refractive index in a direction perpendicular to nx, and nz represents the refractive index in the thickness direction of the retardation film.
