发明名称 SEMICONDUCTOR DEVICE
摘要 The present invention provides a photoelectric conversion device capable of detecting light from weak light to strong light and relates to a photoelectric conversion device having a photodiode having a photoelectric conversion layer; an amplifier circuit including a transistor; and a switch, where the photodiode and the amplifier circuit are electrically connected to each other by the switch when intensity of entering light is lower than predetermined intensity so that a photoelectric current is amplified by the amplifier circuit to be outputted, and the photodiode and part or all of the amplifier circuits are electrically disconnected by the switch so that a photoelectric current is reduced in an amplification factor to be outputted. According to such a photoelectric conversion device, light from weak light to strong light can be detected.
