Gate drive circuit and display apparatus having the same

A display apparatus comprising:

• a display panel including a display area on which a plurality of gate lines, a plurality of data lines and a plurality of pixel transistors are formed and a peripheral area surrounding the display area;
• a data drive circuit outputting data signals to the data lines;
• and
• a gate drive circuit including a shift register in which a plurality of stages are connected one after another to each other, each of the stages including a plurality of transistor, an n-th stage (‘n’ is a natural number) comprising:
• a pull-up part configured to output a high voltage of an n-th gate signal using a high voltage of a clock signal in response to a high voltage of a control node;
• a control pull-down part configured to pull-down a voltage of the control node into a low voltage in response to a carry signal outputted from at least one of a set of subsequent stages of the n-th stage and receiving a back-bias voltage corresponding to the low voltage;
• and
• a carry part configured to output the high voltage of the clock signal as an n-th carry signal in response to a high voltage of the control node.
