A display device is provided. The display device includes a display panel, a gate driver, and a data driver. The display panel includes a plurality of pixels connected to a plurality of gate lines for receiving gate signals, a plurality of data lines for receiving data voltages, and a storage line for receiving a storage voltage. The gate driver is configured to generate the gate signals. The data driver is configured to operate individually in first and second frequency periods to generate the data voltages. The data voltages include a positive data voltage and a negative data voltage, and polarities of the data voltages are inverted every two data lines during the first frequency period and inverted every data line during the second frequency period.
