Abstract
Discussed are a glass patterned retarder stereoscopic 3D display device and a method for fabricating the same. The device is capable of enhancing a viewing angle in upper and lower directions and an aperture ratio by forming light shielding patterns on a rear surface of a color filter substrate. Further, the device is capable of preventing scratches occurring on the light shielding patterns due to a polishing belt, by forming high hardness polymer on the light shielding patterns and removing stair-steps of a rear indium tin oxide (ITO).
