Radiation image detector

A radiation image detector comprising the following layers stacked on top of another:

• a charge generation layer that generates charges by receiving radiation;
• and
• a detection layer including:
• multitudes of pixels, each having a collection electrode for collecting charges generated in the charge generation layer, a storage capacitor for storing charges collected by the collection electrode, and a TFT switch for reading out charges stored in the storage capacitor;
• multitudes of scanning lines for switching ON/OFF the TFT switches;
• and multitudes of data lines through which charges stored in the storage capacitors are read out, wherein:
• each of the storage capacitors is formed between a storage capacitor electrode connected to the drain electrode of a TFT switch and the scanning line connected to a TFT switch adjacent to the TFT switch to which the drain electrode belongs;
• an array of the TFT switches is divided into upper and lower halves for driving;
• each of the data lines is divided into upper and lower halves;
• and
• a dummy wire is provided at the division boundary section of the upper and lower halves of the array of the TFT switches for forming a storage capacitor of a pixel disposed at the division boundary section.
