Radiation detection element, radiograph detection panel, and radiograph detection device

The present invention provides a radiation detection element that avoids a narrowing of the inter-wiring pitch of signal lines. Namely, the shape of pixels configuring the radiation detection element is caused to hexagonal, and the pixels are arrayed in the form of a honeycomb. Also, the configuration is such that TFT switches are disposed to the left side or the right side from the pixel centers in a manner so that the left-right disposition of the TFT switch position in each pixel differs for each pixel column, and the common ground wiring, which affixes the storage capacitor lower electrode of an electric charge storage capacitor at a predetermined potential, is disposed approximately linearly below the pixel electrodes.
