Radio wave reflecting device

Abstract

A radio wave reflecting device includes a radio wave reflecting element and a solar cell. The radio wave reflecting element includes a first substrate provided with bias electrodes arranged in a matrix, a second substrate provided with a common electrode facing the first substrate and overlapping the bias electrode, and a liquid crystal layer between the first substrate and the second substrate. The solar cell includes a light guide having a first surface and a second surface opposite the first surface and a side surface between the first surface and the second surface and a light-receiving portion provided along the side surface. The second surface of the solar cell is arranged to face the first substrate of the radio wave reflecting element, and a light receiving surface of the light-receiving portion is arranged on a side of the light guiding portion.
