Abstract
An X-ray imaging apparatus utilized in an imaging analysis apparatus that includes plural charge conversion devices for converting irradiated X-rays into electric charge and corresponding plural charge storage devices for storing the converted electric charge. Each charge conversion device and charge storage device represent a pixel in an image and are read by a thin film transistor. A thin film diode is connected to each charge storage device to discharge excessive stored voltage. The thin film diode has a Metal-Insulator-Metal (MIM structure), a Metal Semi-Insulator (MSI structure), or a Back-to-Back (BTB structure).
