Abstract
A liquid crystal lens structure is disclosed, comprising a first substrate and a second substrate each having oppositely arranged sides, a first side and second side. A liquid crystal layer is disposed between the first substrate and the second substrate, in which first side of the first substrate and second side of the second substrate are proximate to the liquid crystal layer. A first transparent conductive layer is disposed between the first substrate and the liquid crystal layer. A second transparent conductive layer is disposed on the second side of the second substrate, in which the second transparent conductive layer comprises a circular opening and a circular electrode in the circular opening. Thus, the invention can provide better response time and improve efficiency of the liquid crystal lens structure.
