Abstract: A display device can include a left ripple transistor provided in a left stage to remove ripple occurring in a Q node of the left stage, and a right ripple transistor provided in a right stage to remove ripple occurring in a Q node of the right stage. These ripple transistors perform an on operation and an off operation repeatedly and simultaneously.
