Abstract
An electrically-driven liquid crystal lens, which can achieve not only a gentle parabolic lens plane when being realized via alignment of liquid crystals based on a changed electrode configuration, but also a reduced cell gap of a liquid crystal layer and a stable profile even in a large-area display device, and a stereoscopic display device using the same are disclosed.
