Abstract: A liquid crystal material, a liquid crystal display panel, and a method for manufacturing the liquid crystal display panel are disclosed. A liquid crystal material is used to form a polymer film on a substrate on which no PI layer is provided so as to realize normal display of the liquid crystal panel. Meanwhile, realiability of the panel can be improved, a voltage holding rate can be improved, and poor alignment of the self-alignment liquid crystal material, afterimage, and other problems can be solved.

Abstract: The invention relates to the field of liquid crystal technology, and more particularly to an alignment film being applied in a PSVA liquid crystal display panel and including a first branched chain M and a second branched chain Q bonded on polyimide as a main chain and thus having a structure as shown in the following formula: The first branched chain M is a group applied to deflect the liquid crystal in a distribution state; the second branched chain Q is a group containing nitrobenzophenone or benzoquinonyl. The invention also provides a liquid crystal display panel using the alignment film. The invention can effectively suppress the broken bright point issue of panel and thereby improve panel quality.

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.
