Abstract:
A gate driver and a display device including the gate driver are discussed. The gate driver in one example includes a shift register configured to control charging and discharging of a Q node and a QB node, and i output buffers sequentially connected to the shift register, where i is a natural number of at least 2. Each output buffer is configured to output a gate signal to a corresponding gate line in response to a voltage of the Q node and a voltage of the QB node. The gate driver further includes a dummy output buffer connected to the last stage of the shift register and configured to output a dummy signal to a dummy line in response to the voltage of the Q node.
