The present invention discloses a liquid crystal display and a driving method thereof to speed up a bend alignment at an initial operation such as right after power on in the liquid crystal display with OCB mode. According to the present invention, the LCD, which includes a LCD panel, a source driver outputting image signals and a gate driver sequentially outputting scanning signals, at an initial operation, is controlled to output external bias voltages to common electric lines and simultaneously to stop the driving of the gate driver and the source driver, according as a first time passes, is controlled to output specific common electrode voltages thereto instead of the external bias voltages and simultaneously to perform a driving of the source driver and the gate driver. As a result, at an initial operation, by applying high-level bias voltages instead of the common electrode voltages to the common electrode lines and simultaneously stopping the driving of the gate driver, the source driver and a back light, the speed of the initial bend alignment of a liquid crystal with OCB mode can be made to be high.
