Abstract
The present invention provides a liquid crystal vertical alignment agent, and the liquid crystal vertical alignment agent can make the liquid crystal molecules vertically orientated relative to the substrate surface. The liquid crystal vertical alignment agent makes a cheap price, a stable performance and can make the liquid crystal molecules be vertically aligned. The alignment film such as polyimide (PI) in the present liquid crystal display (such as TFT-LCD) can be replaced, which is beneficial for raising the display performance of the liquid crystal display. The present invention further provides a liquid crystal display element, and the liquid crystal display element utilizes the said liquid crystal vertical alignment agent to make the alignment of the liquid crystal molecules in the vertical direction more consistent and have long term stability.
