A kind of liquid crystal composition and photoelectric element

Abstract

The invention discloses a liquid crystal composition and a photoelectric element. The composition is prepared from the following components in percentage by weight: 1% to 40% of a first component, 5%to 55% of a second component and 10% to 70% of a third component, and the weight percentage sum of all the ingredients is 100%. The composition is further prepared from a fourth component, wherein according to the weight percentage, the first component is 1% to 40%, the second component is 5% to 55%, the third component is 10% to 60%, the fourth component is 3.5% to 30%, and the weight percentagesum of all the components is 100%. The liquid crystal composition disclosed by the invention has the advantages of extremely low Tcn, low-temperature storage temperature and low-temperature work temperature; the liquid crystal composition can be used for preparing the photoelectric element; application of liquid crystal display is greatly expanded under severe work conditions especially related toan active matrix addressing displayer and in a reinforced liquid crystal displayer; thus, the liquid crystal composition has great significance in domestication of a military wide-temperature-range liquid crystal display device.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal materials, and in particular relates to a liquid crystal composition and a photoelectric element. Background technique [0002] As is well known in the art, a single liquid crystal compound cannot satisfy all requirements, so the liquid crystal material used for flat panel display is usually composed of 5 to 20 liquid crystal compounds with different characteristics mixed in a certain proportion. For example, there are both polar liquid crystal compound components and non-polar liquid crystal compound components; there are liquid crystal components with high clearing point, and there are liquid crystal components with low clearing point and low viscosity. After the formula is formed, it can learn from each other to obtain the best display performance, and it can be used as a commercial liquid crystal display terminal. However, among all kinds of flat panel displays, liquid crystal displays...
