<p>Provided is an input device capable of effectively preventing internal reflection of the light from the outside, and capable of preventing drawbacks regarding coloring, etc., even if a substrate, etc., of an input panel is structured by a biaxial stretched film. An external light (1) becomes a linearly-polarized light by a polarizing film (22a), and becomes a circularly-polarized light (2) by a ?/4 phase difference film (22b). If the circularly-polarized light (2) is reflected by a surface (30a) of a display panel (30) or an electrode layer in the display panel (30), the light becomes a linearly-polarized light by the ?/4 phase difference film (22b) and is blocked by the polarizing film (22a). If an input panel (21) is formed by a biaxial stretched film and has a birefringence property, because the circularly-polarized light does not pass through the biaxial stretched film, drawbacks regarding coloring, etc., of the reflection light can be prevented.</p> |
