Display device having a voltage provider for generating a gate-on voltage and a kickback voltage

A display device comprising:

• a display panel including a plurality of pixels, and a plurality of gate lines and a plurality of data lines connected to the plurality of pixels;
• a gate driver applying a gate signal to the plurality of gate lines;
• a data driver applying a data signal to the plurality of data lines;
• and
• a circuit board including a voltage provider and a signal channel connecting the voltage provider to the gate driver,
• wherein the gate driver receives, through the signal channel, a gate-on voltage that is gradually changed within one frame and a kickback voltage that is gradually changed within one frame from the voltage provider, and applies the gate-on voltage and the kickback voltage to the plurality of gate lines, and
• wherein the gate-on voltage gradually increases and is applied to the plurality of gate lines including a first gate line having a shortest distance through which the gate signal is applied and a n-th gate line, where n is an integer greater than one, having a longest distance through which the gate signal is applied,
• a kickback time in which the kickback voltage is applied is different for at least one of the plurality of gate lines,
• each of the gate-on voltage and the kickback voltage has a constant level before a gate start signal is applied during a blank period, and a level of the gate-on voltage gradually increases during an active period within one frame, and
• the kickback time at which the kickback voltage is applied to each of the gate lines is determined by Equation below:
