Abstract
A liquid crystal lens unit is provided for use in an autostereoscopic 3D image display. Light passing through the liquid crystal lens unit is refracted by a liquid crystal layer arranged by an electric field. The voltage levels applied to the to the liquid crystal layer are periodically changed thereby periodically oscillating the position of the focus profile of the liquid crystal lens unit. As a result, moiré patterns are removed and display quality is improved.
