摘要： A bidirectional shift register capable of performing a stable shift operation in both directions and an image display device using the same are provided. In forward shift operation, when reference point N1 is at H level, (n+4)-th unit register circuit as a rear stage of the bidirectional shift register outputs pulse G(n+4) in synchronization with clock pulse V (n+4) inputted to (n+4)-th unit register circuit. A backward direction trigger signal VSTB is generated not only at the time of start of backward shift, but also, for example, in period (time t4 to t5) of one-phase clock immediately after G(n+4) is outputted in vertical blanking interval of the forward shift. The backward direction trigger signal VSTB is inputted to gate of a transistor provided to set reference point N1 of (n+4)-th unit register circuit to H level at the time of start of the backward shift.

摘要： A plurality of cascaded unit register circuits which comprises a bidirectional shift register include main stages and dummy stages at the top before the main stages and dummy stages at the bottom after the main stages. A k-th stage outputs a pulse Pk in synchronization with a clock signal with a reference point N1 being at H level. The main stages include terminals NSF and NSB for setting N1 to H to which Pk−1 and Pk+1 are input, respectively, and terminals NRB and NRF for setting N1 to L level to which Pk−2 and Pk+2 are input, respectively. The order of generation of clock signals is reversed according to the direction of a shift, and whether a start trigger signal is applied to a top stage or a bottom stage is switched. Top dummy stages do not have NRB. Bottom dummy stages do not have NRF.
