Provided is a liquid crystal display panel having gate drivers. The LCD panel includes a gate line shift circuit setting a gate line scanning order such that the gate lines are sequentially scanned in units of n gate lines with k-1 gate lines between each pair of adjacent gate lines in each unit according to an interleaving method in response to a gate line-on signal received from a timing control unit outside the LCD panel, wherein the LCD panel reproduces source data output from a source driver outside the LCD panel in the gate line scanning order set by the gate line shift circuit.
