Provided is an active lens structure. The active lens structure has a configuration in which a polarization switching section and a polarization dependent lens section are integrally formed, wherein a lattice structure is formed on an upper surface of a liquid crystal phase polymer layer of the polarization dependent lens section, and the liquid crystal phase polymer layer is aligned in a top-down manner and is used as a lower alignment film of a liquid crystal layer. Therefore, the polarization switching section of the active lens structure can be fabricated without any lower alignment film and any lower glass substrate, so that it is possible to minimize the total thickness and simplifying the manufacturing process.

Active lens structure and method of manufacturing the same

In a transparent electrode based on a metal material having reduced light reflectance, a light absorbing layer having black characteristic is formed on a lower surface, a partition wall, and/or an upper surface of a metal wire, and thus, light reflectance of transparent electrode is minimized. In a method of manufacturing a transparent electrode, the light absorbing layer can be selectively formed on the upper and lower surfaces and the partition wall of the metal wire having a fine line width by using self-aligning and a spontaneous pattern effect. A conductive wire is implemented by using an imprinting process using an elastic body-based stamp, and thus, conductive wires having a fine line width and an excellent aspect ratio can be formed, so that it is possible to improve electric conductivity and transmittance.
