Abstract

A blue-phase liquid crystal composition comprises at least a main liquid crystal compound, a main dopant, a chiral dopant, a reactor monomer and a photoinitiator, wherein the main liquid crystal compound is represented by formula (1) shown in the description, wherein A, B and C represent benzene ring or hexamethylene respectively, and R1 and R2 respectively represent substituted or non-substituted alkyl having 1 to 12 carbon atoms, or substituted or non-substituted alkoxy having 1 to 12 carbon atoms. The main dopant comprises one of the formula (2) and the formula (3) shown in the description. The chiral dopant comprises one of the formula (4) and the formula (5) shown in the description. The reactor monomer comprises one of the formula (6) and the formula (7). R and R' respectively represent substituted or non-substituted alkyl having 1 to 12 carbon atoms, or substituted or non-substituted alkoxy having 1 to 12 carbon atoms.

Description

【Technical field】 The invention relates to a blue phase liquid crystal composition and a blue phase liquid crystal panel. 【Background technique】 With the vigorous development of display technology, consumers have higher and higher requirements for display image quality. In addition to the requirements for the resolution, contrast ratio, viewing angle, gray level inversion, and color saturation of the display, the consumers also have high requirements for the display. The specification requirements of the response time (response time) are also increasing day by day. In order to meet the needs of consumers, display-related companies have invested in the development of blue phase liquid crystal displays with fast response characteristics. However, the disadvantage of the current blue-phase liquid crystals used in displays is that the driving voltage is too high. Therefore, how to reduce the driving voltage of the blue-phase liquid crystal display is one of the problems tha...
