| titleOfInvention | Dichroic Dyes and Liquid Crystal Display Devices |
| abstract | The present invention relates to a dichroic dye and a liquid crystal display device, wherein the dichroic dye is -5 ° C in a liquid crystal display device in which a liquid crystal layer containing a liquid crystal and a dichroic dye is provided between a pair of substrates having electrodes on the surface thereof. The sum of the transition enthalpy change and melting enthalpy change per unit weight from -5 ° C to melting point is ΣΔHtr, m, and the sum of the transition entropy change and melting entropy change per unit weight from -5 ° C to melting point is ΣΔStr, m. In this case, it indicates that the value of the following formula 1 is an anthraquinone pigment of 0.08 or less,n n n n n Y = {ΣΔHtr, m / 268-ΣΔStr, m} (kJK -1 kg -1 )n n n n n It is characterized by providing a dichroic dye comprising an anthraquinone dye having high light resistance and high solubility in liquid crystals, and providing a guest-host liquid crystal display device capable of realizing bright and clear color display. . |
