Abstract
As an input device capable of suppressing the occurrence of an optical issue and of achieving sufficient strength even if the input device is thin, an input device is provided which includes a first substrate formed into a light-transmissive curved surface and having optical isotropy or uniform optical uniaxial anisotropy in plane, a first electrode layer disposed on a surface of the first substrate, a second electrode layer opposing the first electrode layer, and a space adjusting resin layer disposed between the first electrode layer and the second electrode layer, being light-transmissive, and having optical isotropy.
