Abstract
A plurality of photoelectric conversion sections correspond respectively to a plurality of pixels arranged on a detection surface for converting incident X rays into charge. A plurality of charge storage sections store the charge converted by the plurality of photoelectric conversion sections, respectively. A plurality of transfer TFTs read out the charge stored in the plurality of charge storage sections, respectively. A plurality of protective TFTs have an end thereof connected to the each input terminal of the plurality of transfer TFTs and sweep out from the other end thereof the charge stored in the charge storage sections when the voltage applied thereto exceeds a predetermined voltage level lower than the breakdown voltage of the transfer TFTs.
