Abstract
The present invention relates to a stereoscopic image display device including an active barrier for varying a barrier display pattern so as to display various stereoscopic images. In further detail, the stereoscopic image display device includes a display panel, a barrier, a barrier driver, and a controller. A stereoscopic image is displayed on the display panel. The barrier is placed corresponding to the display panel, and includes a plurality of liquid crystal cells arranged in a matrix format. The barrier driver drives the barrier such that the barrier display pattern may be a display pattern corresponding to the image signal by controlling the respective plurality of liquid crystal cells to become selectively transparent or opaque based on the mode information signal.
