The embodiment of the present invention provides a display device comprising; a display panel; a level shifter which is connected to the display panel and outputs clock signals; a shift resister which is made of stages capable of shifting a gate output pulse in response to the clock signals. A n^th stage of the stages comprises; a pull-up transistor part which includes a first pull-up transistor which outputs a x^th clock signal to a first output end of n^th stage in response to potential of a Q node and a second pull-up transistor which outputs the x^th clock signal to a second output end of the n^th stage; a pull-down transistor part which includes a first pull-down transistor which outputs a first low potential voltage to the first output end of the n^th stage in response to the potential of the Q node and a second pull-down transistor which outputs a second low potential voltage lower than the first low potential voltage to the second output end of the n^th stage; a Q node charging and discharging part which charges and discharges the Q node; a QB node charging and discharging part which charges and discharges a QB node; a sub discharging part which discharges the Q node to the first low potential voltage with different first and second times. |
