PURPOSE: A method for a driving gate line, a gate driving circuit performing for the method and a display apparatus having the gate driving circuit are provided to prevent a malfunction of a display device by maintaining the output of a gate driving circuit a gate off voltage. CONSTITUTION: In a method for a driving gate line, a gate driving circuit performing for the method and a display apparatus having the gate driving circuit, gate signals are applied to gate lines (GL1-GLn). Gate signals are generated from a plurality of shift register(SRC1-SRCn). A plurality of shift registers are connected to a plurality of gate lines. Gate signals are intercepted during a vertical blanking interval. The gate-off-voltage is applied to the gate lines during the vertical blanking interval.
