摘要： Provided is a display device including a display panel, a data driver, a gate driver, and a timing controller. The display panel includes first and second pixel line groups each including k (k is a natural greater than 1) pixel lines, and each of the pixel lines includes a plurality of pixels connected to the same gate line. The data driver supplies an image data voltage to the pixels on the basis of input image data. The gate driver supplies a gate pulse to the gate line. The timing controller controls a driving timing of the data driver and the gate driver, sequentially writes the image data voltage into pixel lines belonging to the first pixel line group during an image data write period and simultaneously writes a black data voltage into pixel lines belonging to the second pixel line group during a black data insertion (BDI) period. The timing controller changes an interval between timings for writing the black data voltage from a start timing of a frame on a frame-by-frame basis.
