Abstract
An X-ray flat panel detector includes an X-ray photosensitive film which generates signal charges upon being exposed to incident X-rays, pixel electrodes which are arrayed in contact with the X-ray photosensitive film, a bias voltage application unit which applies a bias voltage to the X-ray photosensitive film so as to make the pixel electrodes collect holes or electrons, which serve as the signal charges generated by the X-ray photosensitive film and have a higher mobility, capacitors which are arranged in correspondence with the pixel electrodes and store the charges generated by the X-ray photosensitive film, switching thin-film transistors which are arranged in correspondence with the pixel electrodes and read the charges in the capacitors, scanning lines which supply a control signal to OPEN/CLOSE-control the switching thin-film transistors, and signal lines which are connected to the switching thin-film transistors to read the charges when the switching thin-film transistors are opened.
