PURPOSE: A liquid crystal display is provided to improve the image quality of a moving picture and a still image by using a previous image signal and a current image signal to correct an image signal. CONSTITUTION: In a liquid crystal display, a still image determination unit(670) receives an image signal before a frame and a current image signal. The still image determination unit determines whether the current image signal is normal or not. A first correction unit(610) receives the current image signal and outputs a first current correction image signal or the current image signal. A second correction unit(620) receives the current image signal and outputs a second current correction image signal or the current image signal. A data driver supplies the second current correction image signal or the current image signal to a pixel.
