Abstract

The invention provides an LCOS (Liquid Crystal on Silicon) display device and a manufacturing method thereof. The method comprises the steps: providing a substrate; forming a superlattice stack structure on one face of the substrate; forming an antireflection layer on the superlattice stack structure, and forming an electrode layer on the other face of the substrate; laminating the substrate to a liquid-crystal silicon wafer through the electrode layer. According to the LCOS display device provided by the invention, ultraviolet light emitting from the LCOS display device is absorbed by using the superlattice stack structure, so that the problem that the existing LCOS display devices are subjected to afterimage or permanent darkening due to ultraviolet light erosion is solved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to an LCOS display device and a manufacturing method. Background technique [0002] LCOS (Liquid Crystalon Silicon) display device is a new type of reflective projection display device, which uses semiconductor silicon technology to control liquid crystal and then "projects" a color picture. Compared with transmissive LCD (Liquid Crystal Display) and DLP (Digital Light Procession) display devices, LCOS display devices have the characteristics of high light utilization efficiency, small size, high aperture ratio, and mature manufacturing technology. It can easily achieve high resolution and fully color performance. The above-mentioned advantages make the LCOS display device have great advantages in the application field of large-screen display in the future. [0003] figure 1 A schematic structural diagram of an LCOS display device in the prior art is shown. Depend on figur...
