Gate driving apparatus and display device including the same

A display device comprising:

• a substrate comprising a display region in which a plurality of pixels are arranged and a non-display region which is a region excluding the display region;
• and
• a gate driver comprising a gate driving apparatus which is formed in the non-display region,
• wherein the gate driver comprises a plurality of stages arranged sequentially, each stage is adapted to output a gate signal and comprising first output lines and a second output line, wherein the first output lines are connected to a gate line corresponding to each of the stages and are adapted to transmit the gate signal to a plurality of pixels coupled to the gate line, the second output line is adapted to transmits the gate signal to a preceding stage of each of the stages, and the first output lines and the second output line share one contact pad.

A display device comprising:

• a liquid crystal panel comprising a first substrate comprising a display region on which a plurality of gate lines extending along a substantially row direction and substantially parallel to each other, a plurality of data lines extend along a substantially column direction and substantially parallel to each other, a plurality of pixel switching devices and a plurality of pixel electrodes are disposed and a non-display region which is a region excluding the display region and a second substrate on which a plurality of color filters and a common electrode are formed and a liquid crystal layer interposed between the first substrate and the second substrate;
• a timing controller adapted to receive input control signals and to output a first control signal and a second control signal;
• a data driver adapted to receive an image signal and the first control signal from the timing controller and adapted to provide image data voltages, which correspond to the image signal to the plurality of data lines and wherein the first control signal received from the timing controller controls operation of the data driver;
• a clock generator adapted to receive the second control signal from the timing controller and adapted to output a clock signal and a clock bar signal using a gate-on voltage and a gate-off voltage in response to receiving the second control signal from the timing controller;
