In this work, we investigate the stabilization of bend alignment and its mechanism in pi-cell consisting of polymer-walls formed by local photo-polymerization under electric field using liquid crystal/polymer composites. This fabricated-cell can be stabilized into the bend configuration and has no need for the initialization voltage to induce the splay-to-bend transition. We observed the configuration of the changes in the liquid crystal molecules during the splay-to-bend transition for pi-cells with polymer-wall structures, which were arranged in a square grid by controlling parameters, such as a geometric construction between rubbing and wall directions, a pre-tilt angle on substrates, and an orientation of polymer-wall. As the result, we found that the free energy based on three-dimensional alignment formed in both interfaces of the polymer walls and substrates greatly worked for the stabilization condition.
