Title: SCANNING SIGNAL LINE DRIVE CIRCUIT AND DISPLAY DEVICE PROVIDED WITH SAME
Abstract:
Provided is a monolithic gate driver that operates with relatively few circuit elements. A component circuit constituting each stage of a shift register comprises: two output terminals (61, 62) connected to a scanning signal line; two thin-film transistors (MA1, MB1) in which an output control clock signal is provided to drain terminals, and source terminals are connected to the output terminals; a first node (N1) connected to the two thin-film transistors (MA1, MB1); a first node control circuit (420); and an input terminal (41) that receives a set signal (S). In a configuration such as this, the first node (N1) changes from an off-level to an on-level on the basis of the set signal (S). The first node control circuit (420) changes the first node (N1) from an on-level to an off-level.
