摘要： The present application discloses a color resist material, a filter, and a preparation method thereof. The color resist material is a trimer structure formed by polymerizing phthalocyanine dyes, wherein groups with double bonds are introduced on the phthalocyanine dyes to construct a three-molecule complex by a complexing agent, and the phthalocyanine dyes are connected by the double bonds to form a trimer structure. The color resist material with the trimer structure is stably stored in a photoresist liquid and has excellent solvent resistance, while maintains good solubility. Accordingly, a filter made of the color resist material has high transmittance and good optical performance.

摘要： A liquid crystal composition includes a component A composed of one or more liquid crystals with negative dielectric anisotropy and a component B composed of one or more compounds selected from a general formula I, where the optical anisotropy of the liquid crystal composition is larger than 0.14. The elastic coefficient of a liquid crystal system is adjusted by introducing a bi-mesogenic compound into a negative liquid crystal or a negative liquid crystal mixture. When the liquid crystal composition is used for the dimming device, the minimum light transmittance of the dimming device in the dark state can be significantly reduced, the adjustment range of the light transmittance in the light state and the dark state can be expanded, and the haze in the dark state can be increased, thereby broadening the use range.
