Title:
IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/161134
Kind Code:
A1
Abstract:
Provided is a multi-functional imaging device. This imaging device has first to fourth light-receiving elements and first and second functional layers. Each of the first to fourth light-receiving elements is a photoelectric conversion element having sensitivity to light of different wavelengths. The first and second functional layers respectively have first and second transistors. The first functional layer and the fourth to first light-receiving elements are stacked in this order on the second functional layer. The first to fourth light-receiving elements each have stacked thereon a first conductive layer, a first buffer layer, a photoelectric conversion layer, a second buffer layer, and a second conductive layer in this order. The photoelectric conversion layers include an organic compound, and the first buffer layers and the second buffer layers 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.
