Abstract:
A liquid crystal light-adjusting film includes a polymer material substrate and a plurality of elliptical crystal cells. The polymer material substrate has a light incident surface and a light exiting surface opposite to each other. A direction from the light incident surface to the light exiting surface is a thickness direction of the polymer material substrate. The elliptical crystal cells are disposed in the polymer material substrate. A long axis direction of each of the elliptical crystal cells is arranged along a first direction perpendicular to the thickness direction, and each of the elliptical crystal cells comprises a plurality of liquid crystal molecules. A manufacturing method of the liquid crystal light-adjusting film and a backlight module using the liquid crystal light-adjusting film are also provided.
