Liquid-crystal optical modulation element |
| abstract |
The present invention provides a liquid-crystal optical modulation element that uses a homeotropically aligned liquid-crystal composition and is capable of faster response times with a lower drive voltage. This liquid-crystal optical modulation element has the following: a first substrate (10) and a second substrate (20) between two polarizers, the polarization planes of which are perpendicular to each other; and a pair of electrode structures (24, 24) that generate an electric field that is substantially parallel to the surfaces of the substrates. The substrates have homeotropic-alignment films (12, 22), at least one of which has the ability to align the c-directors of liquid-crystal molecules so as to point the same direction. Either a ferroelectric liquid-crystal composition that has a chiral smectic C phase or a liquid-crystal composition that has negative dielectric anisotropy and has an achiral smectic C phase is sandwiched within a liquid-crystal-composition layer (31) at an azimuthal angle of 35-55° with respect to the electric field generated by the pair of electrode structures (24, 24), and the electric field generated by the electrode structures (24, 24) is used to change the birefringence of the liquid-crystal-composition layer (31) so as to modulate the optical transmittance. |
