Abstract
Embodiments of the present invention disclose a liquid crystal display panel and a manufacturing method thereof. The liquid crystal display panel comprises two substrates disposed opposite to each other and a liquid crystal layer filled between the two substrates, and the liquid crystal layer is formed from a mixture, comprising discotic liquid crystal, nematic liquid crystal and photoinitiator, by UV-light irradiation; the mixture comprises 5%˜50% by mass of discotic liquid crystal, 40˜90% by mass of nematic liquid crystal, and 0.05%˜10% by mass of photoinitiator. The liquid crystal panel can have reduced response time.

A manufacturing method for a liquid crystal display panel, comprising:
- forming an alignment layer by applying an aligning agent on at least one of two substrates adapted for manufacture of a liquid crystal panel;
- mixing discotic liquid crystal, nematic liquid crystal and photoinitiator and stirring with protection from light to obtain a mixture in which the discotic liquid crystal and the nematic liquid crystal are mutually-miscible at ambient temperature in the absence of additional solvent(s);
- adding dropwise the mixture onto the substrate formed with the alignment layer, with protection from light, and then performing cell-assembling with protection from light;
- and
- irradiating the substrates after cell-assembling with UV-light, so that the discotic liquid crystal is polymerized under action of the photoinitiator to form a discotic liquid crystal polymer network,
- wherein, in the mixture, the mass percentage of nematic liquid crystal is 40-90%, the mass percentage of discotic liquid crystal is 6-9%, and the mass percentage of photoinitiator is 0.05-10%;
- and
- in the mixture, a plane-direction of main discs of the discotic liquid crystal is parallel to a long-axis direction of the nematic liquid crystal.
A liquid crystal display panel, comprising:
- two substrates disposed opposite to each other and a liquid crystal layer filled between the two substrates, wherein the liquid crystal layer is formed from a mixture, comprising discotic liquid crystal, nematic liquid crystal and photoinitiator, by UV-light irradiation;
- the mixture comprises 6%˜9% by mass of discotic liquid crystal, 40˜90% by mass of nematic liquid crystal, and 0.05%˜10% by mass of photoinitiator;
- and the discotic liquid crystal and the nematic liquid crystal are mutually-miscible in the mixture at ambient temperature in the absence of additional solvent(s);
- and
- in the liquid crystal layer, a plane-direction of main discs of the discotic liquid crystal is parallel to a long-axis direction of the nematic liquid crystal.
