A thin film image pickup element which consists of a photoelectric converter including a transparent electrode, a semiconductor layer, an opaque electrode and first insulator layer, and a switching element including first and second upper electrodes, another semiconductor layer, a gate electrode and a passivation film covered on the gate electrode. A two-dimensional thin film image pickup device consists of a plurality of such thin film image pickup elements by stereoscopically laminating a plurality of photoelectric converters and switching elements with the back surface used as wiring region. The device can read two-dimensional original documents without using a reducing optical system.
