Silicon-based liquid crystal device, manufacturing method thereof and silicon-based liquid crystal display panel

The invention provides a silicon-based liquid crystal device, a manufacturing method thereof and a silicon-based liquid crystal display panel. The silicon-based liquid crystal device comprises: a substrate; at least two pixel electrodes which are arranged on the substrate, wherein the tops of the side walls of every two adjacent pixel electrodes are close to each other relative to the bottom; andan insulating barrier layer which is positioned on the substrate and is filled between the side walls of the two adjacent pixel electrodes, so as to enable the two adjacent pixel electrodes to be isolated from each other through the insulating barrier layer. According to the technical scheme, stray light can be prevented from being reflected into the silicon-based liquid crystal optical system bythe silicon-based liquid crystal device, so that the contrast ratio of an image is prevented from being reduced, the light reflectivity is improved, and the display effect of the silicon-based liquidcrystal display panel is im
