Embodiments are described that simultaneously block glare arising from the reflection of polarized sunlight and can also allow a polarized liquid crystal display (LCD) to be clearly viewed. Embodiments may be useful for use as polarized sunglasses. Embodiments operate by using a unique property of a circular polarizer. One side of the circular polarizer substantially blocks the transmission of incident polarized light whereas the other side allows substantially complete transmission of incident polarized light. Using these opposite behaviors, polarizing sunglasses can be constructed in which the top portion uses a first side of the circular polarizer to block the polarized glare and the lower portion uses a second side of the circular polarizer, opposite from the first side, to view the LCD. Because two different polarizers are used, these sunglasses are called dual-polarization sunglasses to differentiate them from the traditional linear polarizer sunglasses

Disclosed is an input device that can effectively prevent internal reflection of light from the outside, and moreover, with displayed light being circularly polarized light, can prevent the displayed light becoming darker or colored when viewed by a user wearing polarizing sunglasses. Of a capacitance input panel (40), a front substrate (42) and a back substrate (41) having a translucent electrode layer are each configured from a/4 retardation film, and an insulating layer (43) is formed from a polarizing film. External light (1) passes through the input panel (40), becoming circularly polarized light (2).
