Abstract
A holographic polymer dispersed liquid crystal (HPDLC) device is useful for color reflective LCD because it requires neither polarizer nor color filter. HPDLC devices with high reflectivity have been prepared by controlling the phase separation temperature of the HPDLC precursor. The acceleration of the phase separation is one of the guides for HPDLC with high reflectivity. In addition to this, a multi-layered HPDLC device and a HPDLC device having two gratings in a pixel have also been prepared.
