<p>PROBLEM TO BE SOLVED: To reduce the scale of a circuit, without having to perform the adding and the changing of a manufacturing process in the peripheral driving of a liquid crystal display device. SOLUTION: An SWpa, which is a P-ch TFT and an SWpb being a P-ch TFT are connected respectively to a signal line S1, and a signal line S2 and source electrodes of the SWpa, SWpb are connected to a common video bus P1 having a positive polarity. At this time, contact holes 221 in a P-ch source electrode 220 are constituted, so as to be shared with SWpa, SWpb.</p> |
