To achieve a radiation detection panel capable of outputting a signal for generating an accurate pixel signal regardless of the performance of a conversion unit, a detection circuit that outputs a signal used for generating a pixel signal includes a first output circuit that outputs a signal due to afterglow, and a second output circuit that outputs a signal including both a signal based on radiation emission and a signal due to afterglow. Transistors using an oxide semiconductor material for a channel formation region are used as some transistors included in the first and second output circuits. In the radiation detection panel having this structure, the signal (a first signal or a second signal) can be held in each output circuit； therefore, after all output circuits hold the signal (the first signal or the second signal), the first signal and the second signal can be sequentially output from detection circuits.為實現可輸出用於產生與轉換單元之性能無關之準確像素信號之信號的輻射檢測面板，輸出用於產生像素信號之信號的檢測電路包括第一輸出電路，其輸出因餘暉之信號；及第二輸出電路，其輸出包括根據輻射發射之信號及因餘暉之信號的信號。將氧化物半導體材料用於通道形成區的電晶體被用作該第一輸出電路及該第二輸出電路中所包括之若干電晶體。在具有此結構之該輻射檢測面板中，該信號(第一信號或第二信號)可保持於每一輸出電路中；因此，在所有輸出電路保持該信號(該第一信號或該第二信號)之後，該第一信號及該第二信號可相繼從檢測電路輸出。
