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.

Abstract: The present application relates to a method of preparing a metal pattern having a 3D structure, a metal pattern laminate, and use of the metal pattern laminate. According to the method of preparing a metal pattern, the metal pattern having a 3D structure can be effectively formed on a receptor. Especially, the metal pattern having a 3D structure can also be effectively and rapidly transferred to a surface of the receptor, such as, a flexible substrate, to which the metal pattern is not easily transferred. The metal pattern laminate prepared using the method can, for example, be usefully used for metal layers of flexible electronic devices or metal interconnection lines.
