Abstract

A two-dimensional radiation detector for obtaining a radiographic image as converted into electric signals. The detector has a multi-layer structure including a scintilator, a translucent electrode film, a photoconductive film and a scan switch layer. The scan switch layer includes conductors arranged in matrix form and in contact with the photoconductive film, a plurality of FETs corresponding to the conductors arranged in matrix form, and a uniformly planar conductor for successively applying a bias voltage through the FETs to the matrix conductors row by row. Each FET has a drain electrode connected to one of the matrix conductors, a source electrode connected to the uniformly planar conductor, and a gate electrode connected to the drive circuit. The translucent electrode film includes column conductors corresponding to columns of the matrix conductors, each of the column conductors being connected to a signal reading line.
