ABSTRACT:
A vertical driving circuit5includes: a shift register5R having a multistage-connected structure with one stage corresponding to two gate lines G, for transferring a start pulse2VST inputted to a first stage SR1thereof and sequentially outputting shift pulses R1and R2from respective stages; an intermediate gate circuit unit5T disposed so as to correspond to each stage of the shift register, for processing a shift pulse of one stage and a shift pulse of a preceding stage and thereby generating temporally separate intermediate pulses A and B in respective stages; and an output gate circuit unit5U for processing the intermediate pulses A and B and thereby sequentially outputting drive pulses P1to P4to four corresponding gate lines G to sequentially select pixels. The shift register5R includes a dummy additional stage SR0disposed in front of the first stage SR1thereof, and a shift pulse R0outputted from the additional stage is supplied to a first stage NAND1of the intermediate gate circuit unit, whereby a normal intermediate pulse A is outputted from the first stage of the intermediate gate circuit unit.
