Abstract
According to a polarized glasses type stereoscopic image display device and a fabrication method thereof in accordance with the present invention, a light blocking pattern may be formed on a rear surface of the color filter substrate to enhance vertical viewing angle and aperture ratio. Moreover a light blocking pattern may be formed of a metal having a large hardness instead of resin BM and a step height from the rear surface ITO may be removed to prevent a scratch due to an abrasive belt.
