Abstract: An input device includes a light-transmissive panel made of synthetic resin, an electrode layer, a decorative layer disposed on an inner surface of the panel, and an inner resin layer disposed on a surface of the decorative layer. The inner resin layer has a connection pattern on a surface thereof. The connection pattern is in electrical communication with the electrode layer. The input device further includes a flexible printed circuit board joined to the surface of the inner resin layer by thermocompression bonding.

Abstract: A multilayer structure includes a touch sensor and an optical functional layer, the touch sensor including a base member and a transparent electrode layer. The optical functional layer includes a phase-difference layer that gives a phase difference to transmitted light (a specific example of the phase-difference layer is a multilayer configuration formed of a 1/4λ phase-difference layer and a 1/2λ phase-difference layer), and a linear polarizing layer. The optical functional layer is positioned such that a surface thereof on the side on which the phase-difference layer is present faces the touch sensor. In the optical functional layer, the ratio of a retardation at a wavelength of 450 nm to a retardation at a wavelength of 590 nm is less than 0.763, and the slow axis of the base member extends in a direction parallel to the slow axis of the optical functional layer.

Abstract: An input device includes a translucent base material having flexibility, translucent first electrode parts arranged in a sensing region on the base material in a first direction, translucent second electrode parts arranged in the sensing region on the base material in a second direction crossing the first direction, and lead wires that are electrically continuous to the first electrode parts and second electrode parts, the lead wires extending from the sensing region on the base material to a peripheral region allocated outside the sensing region. A bent portion is provided in the peripheral region on the base material. Each lead wire has a flexible conductive member on the bent portion. A covering material is provided so as cover at least part of the flexible conductive member on the base material.
