A spatial light modulator (SLM) with a narrow pixel pitch is required for realizing a holographic display with a wide viewing-zone-angle. As the pixel pitch narrowed, liquid crystal SLMs face a difficulty of the crosstalk between the adjacent pixels. Ferroelectric liquid crystal (FLC) SLMs have an advantage in the pixel crosstalk improvement, which is attributed to the opposite-polarity direct-current driving voltages. We fabricated FLC pixel arrays using a two-layered electrode having predesigned patterns and achieved individual driving of the FLC fine pixels with a 1 × 1-µm pixel pitch. Furthermore, we demonstrated a reconstruction of a 3D holographic image with a wide viewing-zone-angle using the FLC pixel array. |
