Abstract

Disclosed is a display device capable of inhibiting degradation of visual quality that has been caused by crosstalk, without causing an increase in frame size or an increase in power consumption. Each bistable circuit is provided with an output terminal (49) that outputs a state signal; a thin-film transistor (T1), the drain terminal of which is given a high-level potential (VDD), and the source terminal of which is connected to the output terminal (49); a thin-film transistor (T2), the source terminal of which is connected to an area netA that is connected to the gate terminal of the thin-film transistor (T1), and the gate terminal of which is given a clock (CKA); a thin-film transistor (T6) for increasing a potential of an area netZ that is connected to the drain terminal of the thin-film transistor (T2); and thin-film transistors (T4, T5, T3) for lowering each of the potentials of netA, netC, and the output terminal (49). A channel area of the thin-film transistor (T1) is made to be larger than a channel area of the thin-film transistor (T2).

Description

technical field [0001] The present invention relates to a shift register provided in a driving circuit of an active matrix type display device and a driving method thereof. Background technique [0002] Known in the prior art is an active matrix display device in which a plurality of gate bus lines (scanning signal lines) and a plurality of source bus lines (video signal lines) are arranged in a grid pattern, and these plurality of gate bus lines A plurality of pixel forming portions are arranged in a matrix to correspond to intersection points of the plurality of source bus lines. Each pixel forming part includes a TFT (thin film transistor: Thin Film Transistor) as a switching element and a pixel capacitor for holding a pixel value. The sub is connected to the source bus through this crosspoint. The active matrix display device further includes a gate driver (scanning signal line driver circuit) for driving the plurality of gate bus lines, and a source driver (video sign...
