A display apparatus includes a display panel including pixels arranged at an intersection of data lines and gate lines, a source driver IC configured to be disposed on one side surface of the display panel to apply a data voltage to the data lines, a gate driver IC configured to be disposed on any one of two side surfaces which are adjacent to the one side surface of the display panel to apply a gate driving voltage to the gate lines, and a controller configured to receive feedback on a gate driving voltage applied to at least one pixel, detect a distortion of the gate driving voltage applied to the pixel based on the feedback, adjust a level of the gate driving voltage applied to the gate lines to compensate for the distortion of the gate driving voltage, and apply the adjusted gate driving voltage to the gate lines.
