Abstract: A display device is disclosed. The display device includes a first horizontal line having a first sequence of colored pixels, and a second horizontal line having a second sequence of colored pixels. The display device also includes a signal controller for detecting a first input video signal and a second input video signal for pixels respectively disposed on a left outermost vertical line and a right outermost vertical line of the display from an input video signal. The signal controller also corrects the first input video signal and the second input video signal so that they have grayscales that are less than a threshold value. The image quality characteristic is improved by removing the color shift phenomenon of the right and left outermost vertical lines in the display device.
