Display apparatus including bi-directional gate drive circuit

A display apparatus, comprising:

• a display panel having a display area on which gate lines and data lines are formed to cross with each other to display an image and a peripheral area surrounding the display area;
• a main drive circuit configured to generate a first power signal and a second power signal in accordance with a forward direction mode and a reverse direction mode, respectively;
• and
• a gate drive circuit including a signal circuit in which a plurality of driving stages are coupled to each other sequentially, the plurality of driving stages outputting a plurality of gate signals to first terminals of the gate lines, wherein an n-th (‘n’ is a natural number) driving stage comprises:
• a pull-up part configured to output an ON voltage of a first clock signal as an ON voltage of an n-th gate signal;
• a carry part configured to output the ON voltage of the first clock signal as an ON voltage of an n-th carry signal;
• a first pull-down part configured to pull down the ON voltage of the n-th gate signal into a first OFF voltage in response to at least one output signal of a previous driving stage and at least one output signal of a following driving stage;
• a first pull-up/down control part configured to apply a first power signal of ON voltage to a control terminal of the pull-up part in a forward direction mode, and to apply the first power signal of second OFF voltage to the control terminal of the pull-up part in a reverse direction mode, in response to at least one output signal of the previous driving stage;
• a second pull-up/down control part configured to apply a second power signal of the second OFF voltage to the control terminal of the pull-up part in the forward direction mode, and to apply the second power signal of ON voltage to the control terminal of the pull-up part in the reverse direction mode, in response to at least one output signal of the following driving stage;
• and
• an inverting part configured to output the first OFF voltage when carry part outputs an ON voltage, and to output a signal synchronized with the first clock signal when the carry part outputs the second OFF voltage.
