Abstract: The present invention discloses a display panel and a manufacturing method thereof. The display panel includes a plurality of liquid crystal cells, each of the plurality of liquid crystal cells includes cholesteric liquid crystals, and a chiral rotation direction of the cholesteric liquid crystals in one of the plurality of liquid crystal cells is opposite to a chiral rotation direction of the cholesteric liquid crystals in its adjacent ones of the liquid crystal cells, so that the cholesteric liquid crystals films with different rotation directions are designed between adjacent pixels, and one of any two adjacent pixels allows light to pass through, and another one of the two adjacent pixels blocks the light from passing through and reflects the light back into the display device, thereby achieving an object of reducing crosstalk.

Abstract: A liquid crystal material, a liquid crystal display panel, and a manufacturing method thereof are provided. The liquid crystal material includes negative liquid crystal molecules and one or more thiol polymerizable monomers. The display panel uses a polymer film obtained by polymerization of a click chemistry reaction of a “thiol and double bond” system to anchor an orientation state of the liquid crystal molecules on the substrate surface, with few impurities and a low risk of image sticking displayed on the panel.

Abstract: A liquid crystal display device includes a first substrate having a first electrode, a second substrate having a second electrode, a liquid crystal layer, a first polarizer, and a second polarizer. A chiral agent is added in a liquid crystal filled in the liquid crystal layer, a pitch of the liquid crystal is about 8-60 μm; an effective optical path difference of the liquid crystal is about 300-550 nm. By adding a chiral agent to the liquid crystal, changing the angle between the stem electrode and the branch electrode or the angle between the polarization axis of the polarizer and the stem electrode, the transmittance is maximized, thereby achieving high transmittance display.

Abstract: A display panel and a display device are provided in an embodiment of the present disclosure. The display panel includes a first substrate and a second substrate that are disposed opposite each other. A liquid crystal layer is disposed between the first substrate and the second substrate and the liquid crystal layer is doped with a chiral agent. In the present disclosure, the liquid crystal layer of the display panel is doped with a chiral agent and a helical twisting force generated by the chiral agent is used to drive liquid crystal molecules around a pixel to rotate, which can reduce a dark region around the pixel and increase transmittance of the display panel.

Abstract: The present disclosure discloses a display panel and a display device. The display panel includes a plurality of first electrodes positioned in a same pixel unit. The first electrodes include a first sub-electrode and a second sub-electrode. A light wavelength transmittance of a first sub-electrode is different from a light wavelength transmittance of a second sub-electrode, so as to increase a viewing angle of the display panel and solve a problem that the display panel is prone to having color shifts.
