Problems solved by technology
[0002] In the research on chiral liquid crystal filters with high reflectivity, a single-layer template structure is proposed to solve the problem of complex construction process and difficulty in large-scale production and application of multi-layer template structure to realize high reflectivity liquid crystal filter. Realize the preparation of highly reflective liquid crystal filters, the manufacturing process is simple, and can be widely used in the field of color display with low power consumption and high brightness
[0003] Existing liquid crystal filters that can achieve high reflectivity are mainly composed of multi-layer structures, so the manufacturing process is complicated, the cost is high, and it is difficult to apply on a large scale

The invention discloses a manufacturing method of a high-reflectivity liquid crystal filter device, and relates to the technical field of filters. A single-layer cholesteric liquid crystal template with a chiral structure is prepared by using a templating technology; the cholesteric liquid crystal template with the chiral structure is exposed through an ultraviolet lamp to stabilize the cholesteric liquid crystal; the cholesteric liquid crystal template is cleaned with the chiral structure to remove nematic liquid crystals and residual polymers in the cholesteric liquid crystal template to obtain a polymer network with the cholesteric chiral structure, namely the cholesteric liquid crystal template; and cholesteric liquid crystals with opposite chirality is poured into the cholesteric liquid crystal template to obtain the cholesteric liquid crystal device with the multi-chiral structure. Through the preparation method of the single-layer templated multi-chiral structure liquid crystal filter, the preparation of a high-reflectivity liquid crystal device is realized; the preparation method of the single-layer structure is simple in process and has good stability and expansibility.
