Liquid crystals (LCs) are a state of matter which has properties between those of conventional liquids and those of solid crystals. For instance, a liquid crystal may flow like a liquid, but its molecules may be oriented in a crystal-like way. There are many different types of liquid-crystal phases, which can be distinguished by their different optical properties (such as textures). The contrasting areas in the textures correspond to domains where the liquid-crystal molecules are oriented in different directions. Within a domain, however, the molecules are well ordered. LC materials may not always be in a liquid-crystal phase (just as water may turn into ice or steam).
Liquid crystal composite and electro-optical display device comprising same
The invention provides a liquid crystal composite for an active-matrix-addressed electro-optical display device and application of the liquid crystal composite. The liquid crystal compound comprises a compound with a general formula (I) which occupies 10 percent to 30 percent of the total weight of the liquid crystal composite, a compound with a general formula (II) which occupies 5 percent to 30 percent of the total weight of the liquid crystal composite, a compound with a general formula (III) which occupies 10 percent to 40 percent of the total weight of the liquid crystal composite, and a compound with a general formula (IV) which occupies 10 percent to 60 percent of the total weight of the liquid crystal composite. The liquid crystal composite provided by the invention has a relatively high response speed and good low temperature storage stability. The invention further provides the active-matrix-addressed electro-optical display device comprising the liquid crystal composite.
