Patent ID: 7488944

Claim:
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.
