| Abstract(in English) | For the π-cell, typically the bend configuration that exhibits a very fast response speed, the initial splay-to-bend transition has been the cause of a number of problems. We demonstrate a novel design for a π-cell using an in-situ fabricated micro-celled structure, which comprises of polymer walls that can be stabilized into a bend configuration in the initial stage. These devices are formed from a mixture of nematic liquid crystal and multifunctional monomer by a local photopolymeriztion process using non-uniform UV irradiation though a patterned photomask, which separates the formation of the liquid crystal region and the polymer region. In a π-cell containing a large number of mcro-celled polymer structures, which were arranged in a square grid consistent with the photomask pattern, the bend configuration of the liquid crystal was stabilized by a lock-in effect based on the free energy. |
