Abstract: A display panel and a manufacturing method thereof are provided. Each pixel of the display panel includes a transmission region and a reflection region, and the display panel includes a first polarizer, a first base substrate, a first alignment layer, a liquid crystal layer, a second alignment layer, a second base substrate, and a second polarizer. A reflection layer is provided between the second alignment layer and the second polarizer in the reflection region. The liquid crystal layer in the reflection region includes nematic liquid crystal and a polymer network. The liquid crystal layer in the transmission region includes a liquid crystal mixture including the nematic liquid crystal and polymerizable monomers. The polymer network in reflection region is formed by polymerizing the polymerizable monomers in the liquid crystal mixture.

Abstract: A display panel and a display apparatus are provided. The display panel includes a first substrate and a second substrate which are arranged oppositely. A liquid crystal layer is filled between the first substrate and the second substrate, the liquid crystal layer has dielectric anisotropy of parameter in a range from −1 F/m to 1 F/m, a sum of a bending flexural coefficient and a splaying flexoelectric coefficient of the liquid crystal layer is greater than 1 pc/m, and liquid crystal molecules in the liquid crystal layer are deflected by a flexoelectric effect, so that deflecting speed of the liquid crystal molecules in the liquid crystal layer is improved and the response time of the liquid crystal layer is shortened.

Abstract: An embodiment of the present disclosure provides a display device, including: a liquid crystal display panel, comprising a liquid crystal layer including a polymer network formed of a polymerizable monomer; a light guide component, wherein the light guide component is configured such that light from the light source is emitted out from the first surface of the light guide component into the liquid crystal display panel, and in a case that the liquid crystal layer is not applied with a voltage, light from the light source is totally reflected at the liquid crystal display panel without being emitted from a side of the second substrate opposite to the first substrate into the outside air.
