Abstract
There are provided a photoelectric conversion film converting an x-ray to a charge, a switching element composed of a transistor, of which a gate is connected to a corresponding scanning line, a source is connected to the photoelectric conversion film, and a drain is connected to a corresponding signal line, and a accumulation element connected to the photoelectric conversion film and the switching element, accumulating the charged produced in the photoelectric conversion element, a scanning line driving circuit driving the scanning lines, and a signal detection circuit connected to the signal lines and reading out the charge accumulated in the accumulation element. A potential of the photoelectric conversion film and a gate potential of the switching element is set such that an absolute value of a gate-source voltage of the switching element decreases when the charge is accumulated in the accumulation element. The scanning line driving circuit outputs at least two kinds of scanning line voltages that can turn off the switching element.
