Abstract
The present disclosure provides a shift register, the register including n stages, each being configured for performing forward and reverse operations, wherein in the forward operation, a gate signal is output in a forward direction, wherein in the reverse operation, a gate signal is output in a reverse direction, wherein a n-th stage among the n stages includes: a charging unit configured for charging a Q node in a response to a reception of a forward start signal or a reverse start signal; a gate signal output unit configured for outputting a gate signal in a response to the Q node being charged by the charging unit; and a discharging unit configured for discharging the Q node after the output unit has outputted the gate signal, wherein the charging unit includes a dummy transistor and a reverse start transistor, both being connected to the Q node.
