Abstract
An imaging device includes a substrate, photodiode semiconductor layers on the substrate, an upper electrode and a lower electrode sandwiching the photodiode semiconductor layers, and a non-light-transmissive line included in a layer upper than the upper electrode, defining the substrate as the lowermost layer. The photodiode semiconductor layers include a first semiconductor layer, and a second semiconductor layer located between the first semiconductor layer and the lower electrode. The photodiode semiconductor layers have a groove in which the first semiconductor layer is removed in a region covered with the non-light-transmissive line in a planar view. A region overlapping the groove in the planar view does not include the upper electrode. The region overlapping the groove in the planar view includes a part of the second semiconductor layer and a part of the lower electrode.
