Abstract
A solid-state imaging device in the present disclosure includes a semiconductor substrate, pixels, and column signal lines. Each of the pixels includes an amplifying transistor, a selection transistor, a reset transistor, and a photoelectric converting unit. The photoelectric converting unit includes a photoelectric converting film, a transparent electrode, a pixel electrode, and an accumulation diode. The pixel electrode and the accumulation diode are connected to a gate of the amplifying transistor. The amplifying transistor has a source connected to the column signal line and a drain connected to a power source line. The reset transistor has a source connected to the pixel electrode. The selective transistor is provided between the source of the amplifying transistor and the column signal line. A threshold voltage of the amplifying transistor is lower than a voltage of the accumulation diode.
