<p>PURPOSE:To prevent the drain potential of a transistor(TR) for selecting a signal line from varying when the TR turns ON and OFF. CONSTITUTION:On a substrate, plural parallel signal lines 4 and scanning lines 5 which cross the signal lines 4 while electrically insulated are formed and at the positions where the signal lines 4 and scanning lines 5 cross each other, 1st TRs 6 having their source electrodes connected to the signal lines 4 and their gate electrodes connected to the scanning lines respectively are formed. On the input side of a signal line 4, a 2nd TR 3 has its source electrode connected to a signal input terminal 2, its drain electrode connected to the signal line 4, and its gate electrode inserted into and connected to a horizontal scanning circuit, and the gate electrode and drain electrode of the 2nd TR 3 are connected through an inverting means 11 and a capacity element 12. The thin film transistor array which is thus constituted is used for one substrate of an active matrix type liquid crystal display device.</p> |
