Abstract: A display device includes a display panel, and the display panel includes a plurality of gate lines, a plurality of data lines, and a plurality of pixels connected to the plurality of data lines and the plurality of gate lines. A data driver provides data signals to the plurality of data lines. A gate driver sequentially generates gate signals corresponding to a start pulse using a clock signal, and provides the gate signals to the plurality of gate lines. A timing controller provides the clock signal and the start pulse to the gate driver. The gate driver compares a data signal provided to a first data line among the plurality of data lines and at least one of the gate signals to generate a feedback signal. The timing controller sets a delay value of the clock signal based on the feedback signal.
