ABSTRACT:
A liquid crystal display for recognizing a flicker with the naked eyes in a step of inspecting a flicker in the case where a liquid crystal display is driven with a frame frequency of 120 Hz is disclosed.In the liquid crystal display, a timing controller supplies a first frame inversion polarity signal which is used at a first frame inversion and, at the same time supplies a gate start pulse which indicates a supply of a scanning pulse. A frame polarity signal converting means converts a first frame inversion polarity signal into a second frame inversion polarity signal in response to the gate start pulse. And a data driver changes the inputted frame into a second frame inversion in response to the second frame inversion polarity signal.
