摘要：

We demonstrated an A4-paper-sized flexible ferroelectric liquid-crystal (FLC) color displays fabricated by using a new plastic-substrate-based process which was developed for large-sized devices. Finely patterned color filters and ITO electrodes were formed on a plastic substrate by a transfer method to avoid surface roughness and thermal distortion of the substrate, which induce disordering of the FLC molecular alignment. The thickness of an FLC/monomer solution sandwiched by two plastic-film substrates was well controlled over a large area by using flexographic printing and lamination techniques. Molecular-aligned polymer walls and fibers were formed in the FLC by a two-step photopolymerization-induced phase-separation method using UV-light irradiation. A fabricated A4-sized flexible-sheet display for color-segment driving was able to exhibit color images even when it was bent.
