BIMESOGENIC COMPOUND EXHIBITING FAST RESPONSE CHARACTERISTICS BY MEANS OF CONTROLLING THE DIELECTRIC ANISOTROPY OF BOTH MESOGENIC GROUPS

摘要

The present invention relates to a bimesogenic compound exhibiting fast response characteristics by means of controlling the dielectric anisotropy of both mesogenic groups, and more particularly, to a bimesogenic compound exhibiting fast response characteristics by means of controlling the dielectric anisotropic signs of both mesogenic groups in a bimesogenic compound to be either the same or different from one another, such that the bimesogenic compound can be used as a liquid composition in a liquid crystal display device. According to the present invention, the dielectric anisotropy of both mesogenic groups of a bimesogenic compound can be controlled so as to obtain a bimesogenic compound which is ideal for a related mode. When a bimesogenic compound is designed such that both mesogenic groups have different signs of dielectric anisotropy by increasing the revolving speed of liquid crystal molecules, not only can the response time of liquid crystal be increased, but the viewing angle can also be widened.
