Abstract: An actuator device comprises a stack formed from a plurality of photoresponsive layers, which deform in response to light, which are partitioned by respective deformable non-photoresponsive layers. The deformable non-photoresponsive layers guide light between and to the photoresponsive layers, and can follow the deformation of the photoresponsive layers.

Abstract: The present disclosure provides a liquid crystal material, a method of manufacturing a liquid crystal display panel, and a display panel. The display panel includes a thin film transistor substrate, a color film substrate, a polymer layer structure, and a liquid crystal layer. During the preparation, after three different irradiations, the liquid crystal material is directly polymerized into the first polymer layer structure and the second polymer layer structure under the irradiations, eliminating the black matrix structure and the polyimide alignment film structure, improving the display effect of the panel, and reducing preparation costs.
