Abstract
Provided are an alignment film for a liquid crystal (LC) lens, a mold for preparing the same, a method of manufacturing the alignment film, and a method of manufacturing the mold. An alignment film in which an LC lens in which liquid crystals are well aligned, can be effectively manufactured, or a mold for preparing the alignment film can be provided. In particular, in order to implement a shape of a lens, the liquid crystals filled in a nonplanar space, such as a curved surface, are effectively aligned in the LC lens so that the LC lens can be formed. Also, a combined fine pattern can be manufactured using a simple process and can also be applied to a continuous process, such as a roll-to-roll process.
