LIQUID CRYSTAL MATERIAL OF SMECTIC PHASE IN HIGH SCATTERING STATE AND DISPLAY DEVICE THEREOF

摘要

The present invention relates to a high scattering smectic liquid crystal material and display device using the same. The high scattering smectic liquid crystal material contains two or more organic compound of Formula (I). In the present invention, a series of smectic A phase liquid crystals having compact arrangement of crystal domains or a series of smectic liquid crystal mixed materials having a degree of order higher than that of the smectic A phase and an optical texture different from that of the smectic A phase are obtained by mixing a smectic liquid crystal with an organic compound having a high optical anisotropy (”n) or mixing different types of smectic phases. When used in a smectic stable state liquid crystal display pattern, these materials have a high scattering state and can effectively improve the contrast of a smectic liquid crystal display device. The present invention also improves contrast when it used in a reflective smectic liquid crystal display device.
