1. A liquid crystal display device comprising:

  • a display panel configured to display an image, the display panel including a plurality of gate lines and a plurality of data lines;

    a data driver configured to supply the data lines of the liquid crystal panel with data signals corresponding to the image; and

    a gate driver on the liquid crystal panel and including a plurality of shift registers, which are configured to apply output signals sequentially shifted from a start pulse to the gate lines, each of the shift registers including;

    an output portion having an output transistor which includes;

    a gate electrode responsive to a voltage on a first node;

    a source electrode receiving a clock signal;

    a drain electrode connected to the respective gate line and configured to apply the clock signal from the source electrode to the respective gate line according to the voltage on the first node; and

    a top electrode disposed on an uppermost layer and connected to the gate electrode, anda control portion that controls the output portion.
