Abstract
The present invention provides an electromagnetic wave detection element that can raise the speed of image read-out. Scan lines are each disposed to plural pixel lines for each of the pixel lines in a row direction of plural pixels disposed in a matrix array, and switches each TFT switch provided to respective pixels in the plural pixel lines by the respective scan lines. Plural signal lines are each disposed to each of the pixel lines in the column direction of the matrix array. In each of the pixel lines in the column direction, the respective signal line is connected to a different TFT switch from the TFT switches that are connected to the same respective scan line, and the charge accumulated in storage capacitors is read out through each of the signal lines according to the state of the TFT switches.
