Abstract

Ultra-violet nanoimprint lithography was utilized to transfer a one-dimensional nano pattern onto a hydrophilic ultra-violet cured polymer surface for use in liquid crystal displays. A master mold with the one-dimensional nano pattern was initially constructed using laser interference lithography, which is a fast and maskless process that can be employed over a large area. The UV cured polymer showed a hydrophilic characteristic, and was used as a homogeneous alignment layer. The nano-patterned ultra-violet polymer successfully aligned the liquid crystal molecules without defects. Additionally, the liquid crystal cell was characterized by high thermal stability due to the high thermal endurance of UV cured polymer. Therefore, the proposed ultra-violet nanoimprint lithography technique is beneficial for advanced liquid crystal devices with high brightness and resolution with numerous switching components that require a high thermal cost.
