Embodiments of the invention relate to a stereoscopic image display and a method for driving the same. Stereoscopic image display includes a data display unit including a first scan transistor, an active black stripe unit including a second transistor and a third transistor, and a shift register sequentially supplying the gate pulse to each of (2n−1)th gate lines and (2n)th gate lines, where n is a natural number. The first scan transistor supplies a data voltage to a pixel electrode in response to a gate pulse of a (2n−1)th gate line, the second transistor supplies the data voltage to the pixel electrode in response to the gate pulse of the (2n−1)th gate line, and the third transistor supplies a low logic level voltage or a common voltage to the pixel electrode in response to a gate pulse of a (2n)th gate line.
