FIG. 1.

AFM image of thenano sized features which were transferred from a mold pattern into the hybrid type polyimide. The rubbing direction performed on the nanopattern was indicated.

FIG. 2.

Polarizing microscopic images of nematic LCs dropt on the surface rubbed with the roller rotation of on a surface grooved by NIL: (a) when the groove direction denoted by G was placed on optically transmissive axis of a polarizer in the crossed polarizers, (b) when the groove direction is put on 15°, and (c) when the groove direction is put on .

Image of FIG. 3.
FIG. 3.

Bistable nematic LC direction observed on several rotations of rubbing roller with respect to groove’s pitch 200, 400, and .
