Abstract: A liquid crystal display device includes: a plurality of pixels; a timing controller configured to convert an externally input image signal into image data and control the generation of a gamma voltage. The gamma voltage is compensated based on a kick-back voltage generated for each gray level. The gamma voltage generator is configured to generate a compensation gamma voltage that compensates a kick-back voltage under control of the timing controller; and a data driver is configured to convert the image data into a data signal by using the compensation gamma voltage. The plurality of pixels may include a first pixel and a second pixel, which display colors different from each other, and the first pixel and the second pixel display colors of the same gray level by using data signals having voltage magnitudes different from each other.
