Abstract
A light detection device is disclosed. A first cell and a second cell are set in the light detection device. The first cell and the second cell are mutually adjacent. The device includes: a first semiconductor layer of a first conductivity type; a second semiconductor layer provided on the first semiconductor layer, the second semiconductor layer being of a second conductivity type; a first member provided between the first cell and the second cell; a second member provided between the first member and the first cell; and a third member provided between the first member and the second cell. The first to third members are made of a material different from the first semiconductor layer and the second semiconductor layer.
