Abstract
A multifunctional imaging device is provided. The imaging device includes first to fourth light-receiving elements and first and second functional layers. The first to fourth light-receiving elements are photoelectric conversion elements having sensitivity to light of different wavelengths from each other. The first and second functional layers each include first and second transistors. The first functional layer and the fourth to first light-receiving elements are stacked in this order over the second functional layer. In each of the first to fourth light-receiving elements, a first conductive layer, a first buffer layer, a photoelectric conversion layer, a second buffer layer, and a second conductive layer are stacked in this order. The photoelectric conversion layer includes an organic compound, and the first buffer layer and the second buffer layer each include a metal or an organic compound. The first transistor is electrically connected to the first conductive layer of any of the first to fourth light-receiving elements. The second transistor is electrically connected to the first transistor.
