Multiviewable stereoscopic image display device and method for driving the same

A stereoscopic image display device comprising:

• a display panel that displays a 2D image in the 2D mode and displays a 3D image in the 3D mode;
• a control unit that receives first to m-th image data (m is a natural number greater than 2), and in the 3D mode time-divides and sequentially outputs the left-eye image data of each of the first to m-th image data, and then time-divides and sequentially outputs the right-eye image data of each of the first to m-th image data;
• and
• first to m-th liquid crystal shutter glasses that open and close the left-eye shutter and the right-eye shutter in synchronization with each of the first to m-th liquid crystal shutter glass control signals generated from the control unit,
• wherein, in the 3D mode, only the left-eye shutter of each of the first to m-th liquid crystal shutter glasses is opened in synchronization with a period during which the left-eye image data of each of the first to m-th image data is output, and only the right-eye shutter of each of the first to m-th liquid crystal shutter glasses is opened in synchronization with a period during which the right-eye image data of each of the first to m-th image data is output.
