Abstract:
1. A radiation image pick-up device having: a radiation detecting circuit section in which a plurality of pixels for detecting incident radiation are two-dimensionally arranged over a substrate; and a drive circuit section for driving said radiation detecting circuit section, wherein each of said pixels comprise: an MIS-type conversion element for converting the incident radiation into electrical signals; a source follower-type first field effect transistor for reading out electrical signals resulting from the conversion by said conversion element; a second field effect transistor provided to read out the electrical signals of said conversion elements selected row by row by said drive circuit section from said first field effect transistor; and a third field effect transistor provided to reset or refresh row by row said conversion elements read out by said first field effect transistor, wherein the second field effect transistor of a pixel in the nth row, and the third field effect transistor of a pixel in the (n−1)th row are connected commonly to a gate wiring of the nth row.
