Abstract: Embodiment relate to a display panel that modulates 3D image data based on pixel data of adjacent lines. The display panel includes data lines, gate lines, and a plurality of pixels; a data modulation unit. The modulation unit modulates kth pixel data of a jth line in 3D image data based on the kth pixel data of the jth line and kth pixel data of a line adjacent to the jth line. The data driving circuit converts the modulated 3D image data into analog data voltages and outputs the analog data voltages to the data lines. A gate driving circuit sequentially outputs gate pulses to the gate lines.
