[Paper] Fabrication of Alignment-Controlling Sandwiched Spacer with Polysiloxane Elastmer for Fixed-Curvature Liquid Crystal Displays

抄録

In this paper, we have proposed an alingment-controlling sandwiched spacer that controls the alignment of liquid crystals (LC) in fixed-curvature LC displays without using an alignment film and serves as a spacer between rigid curved substrates. This spacer is flexible and does not require additional LC alignment film. The spacer was fabricated by a transfer method using polysiloxane resin. As a result, we fabricated curved LC devices using alignment-controlling spacer and curved glass, and this device can move LC alignment. It was found that the polysiloxane surface causes the liquid crystal molecules to be oriented perpendicularly to the polymer side surface. This device lead to durable curved LC displays without solid stick spacers that break easily.
