Abstract
The present invention provides a radiation detection element and a radiographic imaging device that may provide optimal resolution that corresponds to the purpose of imaging and to imaging speed, and that may suppress increase in device size. Namely, TFTs of plural pixels in a column direction are connected to the same signal lines. When a moving image is imaged, a control signal is output via a control line, the TFTs of the pixels are turned on, and the charges are read-out from sensor sections. Since the two pixels×two pixels are operated as one pixel and the charges are extracted, resolution may be lowered when compared with a still image and a frame rate may be improved.
