Patent ID: 8730144

Claim:
A driving circuit comprising: a plurality of stages driven in response to a start signal, wherein the stages include at least two normal stages, a first dummy stage, and a second dummy stage, wherein each normal stage comprises: a first output part that outputs a gate signal according to an electric potential of a node of the normal stage; a second output part that outputs a carry signal according to the electric potential of the node; a control part comprising: a buffer part that increases the electric potential of the node in response to a previous carry signal output from a previous one of the stages, a first pull-down part that decreases the gate signal to a first voltage in response to a first next carry signal output from a first next one of the stages, and a second pull-down part that decreases the carry signal to a second voltage lower than the first voltage in response to the first next carry signal; and a holding part applies the second voltage to the node in response to receipt of a second next carry signal output from a second next one of the stages, wherein the first dummy stage outputs a first dummy carry signal to the last two normal stages in response to receipt of a last carry signal from the last normal stage and the start signal, and wherein the second dummy stage outputs a second dummy carry signal to the last normal stage in response to receipt of the first dummy carry signal and the start signal.
