“…Lagerwali firstly reported the surface-stabilized ferroelectric liquid crystal (SSFLC) device in 1980, much effort has been devoted to developing a variety of devices, which can be used as a SLM and flat display panel in the information processing area, for its high content, fast response and bistability (memory capability) [1][2][3][4]. FLCs are sensitive to the aligning surface and it is a difficult thing to obtain a desired FLC alignment with large area uniformity.…”

Electrically-controlled 6464 fermelectric liquid crystal spatial light mocMators (FLC-SLMs) were fabricated with a quick response, high contrast ratio and good bistability at the resolution of 10 1mm. The special polymer films aligned SiMs have a quite long operation life. A 1.6 inch 64x80 FLC device for the display aim was fabricated, which e-opmperties have been improved by the modification of the aligning layers and a large area FLC alignment with uniformity can be obtained A FLC light shutter at the aperture of 30mm x30mm was also fabricated and used as a phase-sensitive image system for the investigation offluorescence lifetime.

“…In addition, the response time of SSFLCs is sufficiently rapid (under 1 ms), allowing for the display of dynamic holograms. For these reasons, many devices using SSFLCs have been fabricated, [27][28][29][30][31] but the smallest pitches were 1.25 μm 32) (the modulation ratio, defined below, was not evaluated) and 1.82 μm 33) (modulation ratio, 0.5). Notably, many reports evaluated FLC resolution using a patterned electrode that could deliver only one voltage; no report has dealt with 1 μm pitch electrodes applying individual voltages.…”

We examined the spatial resolution characteristics of surface-stabilized ferroelectric liquid crystals (SSFLCs) to produce an amplitude-type spatial light modulator with 1 μm pitch pixels for wide-field-of-view holographic displays. We compared the resolution of SSFLCs and parallel-aligned nematic liquid crystals (NLCs) using small-pitch stripe-shaped electrodes, and concluded that SSFLCs are superior. The enhanced resolution of SSFLCs is attributable to the symmetrical LC molecular alignment achieved by applying opposite-polarity direct-current voltages; NLCs are aligned using alternating-current voltages.
