Abstract
An active matrix substrate includes a demultiplexer circuit which includes a plurality of DMX circuit TFTs. Each of the DMX circuit TFTs includes a front-gate electrode (FG) supplied with a control signal from one of a plurality of control signal main lines ASW, BSW and a back-gate electrode (BG) supplied with a back-gate signal which is different from the control signal. The plurality of DMX circuit TFTs includes first DMX circuit TFTs (T, T) and second DMX circuit TFTs (T, T). The back-gate electrode of each of the first DMX circuit TFTs (T, T)is connected with a first back-gate signal main line (BGL()) which supplies a first back-gate signal and, the back-gate electrode of each of the second DMX circuit TFTs (T, T)is connected with a second back-gate signal main line (BGL()) which supplies a second back-gate signal which is different from the first back-gate signal.
