Abstract: A stereoscopic image display and a driving method thereof are discussed. The stereoscopic image display includes a data driving circuit that supplies a data voltage to data lines of a display panel; a gate driving circuit that supplies a gate pulse to gate lines of the display panel; and a timing controller that controls operation timings of the data driving circuit and gate driving circuit. The gate driving circuit delays a rising timing of the gate pulse to a point in time after a rising edge time of the data voltage in a 3D mode for displaying a 3D image on the display panel, under a control of the timing controller.
