Light detection device and electronic device

Abstract

The present disclosure relates to a light detection device and an electronic device capable of reducing reflection of incident light depending on an image height position. The light detection device includes a pixel array unit in which a plurality of pixels is arranged in a two-dimensional array. Each pixel includes: a refractive index variation layer having at least two regions in the same layer, the two regions being a first region containing a first matter and a second region containing a second matter; and a photoelectric conversion unit that photoelectrically converts light incident through the refractive index variation layer. An effective refractive index of the refractive index variation layer is configured to differ depending on an image height position of the pixel. The present disclosure can be applied in, for example, a solid-state image capturing device, a light-receiving device of a rangefinding system, or the like.
