If the bent-core molecules exhibit nematic phases, they could have biaxiality due to their molecular shapes. Recently a liquid crystal material containing a thiazole unit as a central core was synthesized and found to exhibit an interesting nematic phase. Under an optical microscope, the Schlieren textures were observed in the nematic phase of a homeotropically aligned cell. In the nematic phase range, we observed a spontaneous orientational change associated with characteristic texture changes, which may provide the information of the nature of the nematic phase. Two reflections were observed at a small angle corresponding to a layer periodicity even in the nematic phase, suggesting the existence of a cybotactic formation of the layer structure. In aligned samples, each peak splits into two. Based on these experimental observations, the possible existence of the biaxial nematic phase will be discussed.

<p>We achieved a super low power consuming LCD panel with an n-FFS mode driven by IGZO-TFTs at low frequency. In this paper, we report the development of a new photo-alignment process for n-FFS, which prevents light-leakage and mura caused by conventional rubbing processes. In addition, we also developed high reliable liquid crystal and photo-alignment materials, which reduce flicker in low refresh rate driving. These technologies have already been applied to the Generation Eight factory, and are being adopted to small/middle sized LCDs for smartphones, tablet PCs, notebook PCs and so on.</p>
