Problems solved by technology

However, due to the similarity in chemical structure between the chiral compound and the cholesteric liquid crystal molecule, the molecular compatibility is good, making it difficult to control its diffusion, so the production process is difficult to control, which leads to the reflection wave of the reflective polarizer. The width is still narrow, and there is still room for further widening

Abstract

The embodiment of the invention provides a reflecting polaroid, a method for producing the same and a liquid crystal display device, which relate to the technical field of liquid crystal display, and the reflecting Polaroid which has both optical compensation performance and broadband reflection performance can be produced. The reflecting polaroid comprises a first substrate, a first alignment layer which is arranged on the first substrate, a chiral coating which is formed on the first alignment layer, a second substrate which is arranged with the first substrate in a box manner and is provided with a second alignment layer, and cholesteric liquid crystals which are filled in a clearance, wherein the chiral coating is formed by coating chiral discotic liquid crystal solution onto the first alignment layer; spacers are arranged between the chiral coating and the second alignment layer for forming the clearance; and the cholesteric liquid crystals are produced by mixing at least nematic liquid crystals, photopolymerization nematic liquid crystal monomers, chiral compound, photoinitiator and thermal polymerization inhibitor.

Description

Technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a reflective polarizer, a method for preparing a reflective polarizer, and a liquid crystal display device. Background technique [0002] With the rapid development of liquid crystal display technology, polarizers used in liquid crystal displays are becoming more and more important. Polarizers are optical components that can turn natural light into polarized light and are an important part of liquid crystal displays. [0003] Because the cholesteric liquid crystal with a special spiral structure has selective reflection characteristics, this special optical performance makes the cholesteric liquid crystal widely used in liquid crystal displays, storage materials, infrared radiation shielding materials and "smart" windows, etc. field. The reflective polarizer made of cholesteric liquid crystal can make the polarizer have the function of selective reflection. [00...
