Abstract: A display device including a plurality of pixels is disclosed. Each of the pixels includes a switching transistor, a plurality of scanning lines connected to the switching transistors and a plurality of data lines connected to the switching transistors. The scanning lines transmit a gate turn-on voltage that turns on the switching transistors and a gate turn-off voltage that turns off the switching transistors and the data lines transmit a data voltage. The gate turn-on voltage is determined based on a maximum value of the data voltage. The gate turn-on voltage based on the maximum value of the data voltage results in high luminance and less crosstalk phenomenon.
