Patent ID: 7777711

Claim:
A display comprising a shift register circuit including: a first shift register circuit portion outputting a first shift signal; a second shift register circuit portion arranged subsequently to said first shift register circuit portion with respect to a scanning direction for outputting a second shift signal; and a logic composition circuit portion, constituted of a plurality of first conductive type transistors turned on with a first voltage supply source, receiving said first shift signal and said second shift signal and outputting a shift output signal by logically compositing said first shift signal and said second shift signal with each other, wherein at least either said first shift register circuit portion or said second shift register circuit portion includes a reset transistor for resetting the voltage supply source of a node outputting said first shift signal or said second shift signal to a second voltage supply source not turning on said transistors of said logic composition circuit portion in response to an output signal output from a shift register circuit portion precedent thereto by at least two stages with respect to said scanning direction.
