Abstract: A display device includes odd-numbered and even-numbered gate lines in a first direction, a plurality of data lines in a second direction, a plurality of pixels, a data and gate driver, and a timing controller. The pixels in a column extending in the second direction are alternatingly connected to a first data line located left of the column and a second data line located right of the column, among the plurality of data lines. The timing controller controls the gate driver and the data driver to sequentially apply a first image and a black image to the pixels connected to the odd-numbered gate lines during a first interval to display the first image on the display panel and sequentially apply a second image and the black image to the pixels connected to the even-numbered gate lines during a second interval to display the second image on the display panel.
