摘要： An optical film includes a plurality of helically arranged liquid crystals and organic solid crystal structures at least partially surrounding the plurality of helically arranged liquid crystals. A method of making the optical film includes obtaining a substrate with an alignment layer and a film of a first solution on the alignment layer. The first solution includes liquid crystals and organic crystal molecules. The liquid crystals form a plurality of helically arranged liquid crystals on the alignment layer. The method also includes forming organic solid crystal structures by crystallizing the organic crystal molecules. The organic solid crystal structures at least partially surround the plurality of helically arranged liquid crystals.

摘要： A PSA-type liquid crystal composition includes a host liquid crystal A and a polymerizable component B, where the host liquid crystal A includes one or more liquid crystal compounds, and the polymerizable component B includes at least one compound selected from compounds of general formula I-1, general formula I-2 and general formula I-3. A liquid crystal display device includes the PSA-type liquid crystal composition above. The PSA-type liquid crystal composition has better intersolubility, cannot be crystallized at a low-temperature environment, can form a relatively stable pretilt angle after the polymerization of the polymerizable component, avoids the image sticking, and inhibits the occurrence of a display defect, such as Zara Particle, during the polymerization.
