Langmuir. 36:8914-8921
Photopolymerization of Langmuir monolayers composed of bifunctional acrylic liquid crystalline (LC) compounds was observed in situ by polarizing optical microscopy. In a dark state, monolayers of the LC compounds formed at an air-water or liquid-liqu

Organic light-emitting diode displays have a cathode composed of a layer of highly reflective metal. Reflection of external light from this layer can be suppressed with a broadband quarter-wave plate. Although various types of quarter-wave plate reta

"Ferroelectric smectic (SmC) phase" Anchoring effects on the polymer films in the liquid crystal (LC) display devices plays key role to create the restoring force to the black state for any types of display modes, such as IPS, STN, VA and OCB etc. On

Azobenzene liquid crystals, possessing two chiral moieties at both of the peripheral ends of the molecular structure, show characteristic chirality-originated liquid-crystalline and physical properties: emergence of stable smectic Q phases, a photoin

We studied the hyper-swollen behavior of a perfluorinated smectic liquid crystal, 11-(4′-cyanobiphenyl-4-yloxy)undecyl pentadecafluorooctanoate (BI), through addition of perfluorinated oils. The studied compound, BI, has a bilayer SmA–SmC phase s

We designed the fast switching & low driving voltage principle with nano slippery interfaces in nematic gels. Confinement effect by the gel network can accelerate the response time of nematic due the localization of director motion as similar way to

Anchoring effects on the polymer films in the liquid crystal (LC) display devices plays key role to create the restoring force to the black state. However, the chiral materials with spontaneous helix, such as deformed helix mode in SmC* (DH-FLC) or t

We present two types of novel side-chain photo-polymers with cinnamoyl moieties for photo-alignment and patterning of the alignment of liquid crystal displays (LCDs). One type is designed for photo-thermal processing; the other comprises co-polymer s
