摘要:
An optical path deflecting element, an optical path deflecting apparatus, an image displaying apparatus, an optical writing apparatus, an optical interconnection apparatus, an optical element, and a fabrication method thereof. The optical path deflecting element includes a pair of transparent substrates, transparent electrode films on the substrates to which a voltage having an inverse polarity is selectively applied, an alignment layer in the inner sides of the substrates, and a liquid crystal layer formed of a chiral smectic C phase between the substrates via the alignment layer and homogeneously aligned by the alignment layer. The optical deflecting element can realize the uniformly-aligned liquid crystal layer more easily than a case in which the liquid crystal is aligned to become in a bistable condition. For this reason, it is possible to improve yield in the fabrication.
