Abstract
A liquid crystal on silicon (LCOS) display device and an electronic device are disclosed. The LCOS display device includes a wafer substrate and a pixel electrode layer over the wafer substrate. The pixel electrode layer comprises a plurality of pixel electrodes, and a reflector stack or at least a stack comprised of, stacked vertically downward, a first high refractive index insulating layer and a first low refractive index insulating layer is arranged between every adjacent two pixel electrodes. By arranging the reflector stacks or stacked layers (in the gaps) between adjacent pixel electrodes, the gaps exhibit higher reflectivity and produce less diffraction noise.
