The invention provides a passive matrix field-sequence liquid crystal displayer and a driving method thereof. The method comprises: a step of turning off a backlight source; a step a of setting the voltages of sectional signal lines at the standard level of a first voltage setting the voltages of common-connection signal lines at the standard level of a second voltage, and setting the voltage difference of the pixel of a liquid crystal display panel as a fully-transparent voltage difference in a preset time period; a step of setting the voltages of the common-connection signal lines as a display common-connection voltage in turn in a corresponding driving period, wherein when the voltages of the common-connection signal lines are set as the display common-connection voltage, corresponding display data are output to the sectional signal lines; and a step of providing a given-color light source corresponding to the display data after a certain period from the step a. In the invention, the pixel reaction time of
