    摘要: A liquid crystal display (LCD) device and a method for driving the LCD device are disclosed. The LCD device includes a frame rate adjusting circuit for controlling a frame rate to be maintained at a 1-fold rate in frame periods other than an Nth frame period (“N” is a multiple of 8 or more), while being increased to an “i”-fold-accelerated rate (“i” is a positive integer of 2 or more) in the Nth frame period, to output reference timing signals in the frame periods other than the Nth frame period, and to output accelerated timing signals in the Nth frame period, a timing controller for generating data and gate timing control signals, based on at least one of each reference timing signal and each accelerated timing signal, and a logic circuit for accelerating a frequency of a polarity control signal in the Nth frame period.
