Abstract
The disclosure provides a shift register including a node controller configured to control charging and discharging of a node Q and a node QB, and an output circuit including a first buffer transistor configured to output a first scan signal, a second buffer transistor configured to output a second scan signal and a third buffer transistor configured to output a carry signal in response to electric potentials of the node Q and the node QB. The first buffer transistor and the second buffer transistor have different channel region widths. The output circuit may further include a first dummy buffer transistor having a common gate and common drain connection structure with the first buffer transistor.
