Abstract
A TFT module includes TFTs; gate bus lines; a plurality of source bus lines; unit electrodes connected with the source bus lines via the TFTs; a gate driver configured to supply a scan signal from a first end of the gate bus lines and a source driver configured to supply a data signal from a first end of the source bus lines, the gate driver and the source driver being provided in a second region lying around a first region in which the unit electrodes are provided; current sensing circuits provided in the second region; and feedback lines. Each of the feedback lines is connected with a corresponding current sensing circuit and with a second end of a corresponding source bus line or gate bus line, the second end being opposite to the first end.
