[Paper] Switching and Response Characteristics of Ferroelectric Liquid Crystal Driven by Small-pitch Electrode for Holographic Displays

We reduced the electrode pitch to 0.7 μm and drove the ferroelectric liquid crystal (FLC) at a low voltage of 1 V to realize a spatial light modulator (SLM) with small pixels for a holographic display with a wide viewing zone angle. Even with an extremely small electrode pitch of 0.7 μm, the FLC could be driven at a low voltage of 1 V. We also evaluated the switching angle and response time of the FLC on the fine-pitch electrodes and found that the switching angle decreases and the response time increases when the electrode pitch is reduced. This work shows the possibility of applying the SLM using the FLC to a holographic display with a wide viewing zone angle.
