Description
Technical Field
The invention relates to a compound capable of realizing self-assembly photoalignment function and a liquid crystal composition containing the compound, and belongs to the field of liquid crystal display.
Background
Currently, alignment of liquid crystal molecules can be achieved using a specific polyimide alignment film. As a method of aligning a liquid crystal alignment film for imparting alignment control ability, a brush polishing method has been widely used. However, the brush polishing method for rubbing the surface of a liquid crystal alignment film containing polyimide or the like has problems of dust generation and static electricity generation. Further, in recent years, the liquid crystal display element has been made higher in definition and the surface of the liquid crystal alignment film cannot be uniformly rubbed with a cloth due to irregularities caused by the electrode on the corresponding substrate or the switching active element for driving the liquid crystal, and thus uniform liquid crystal alignment cannot be achieved.
On the other hand, the polymerizable mesogenic unit RMs is a very popular and important subject in the display industry, and the possible application fields include Polymer Stabilized Alignment (PSA) liquid crystal display, polymer stabilized blue phase (PS-BP) liquid crystal display, and patterned retardation film PATTERN RETARDER FILM. In a liquid crystal display element in which a polymer is stably aligned, the alignment of liquid crystal molecules can be controlled by using the polymer.
In the prior art, there is disclosed a report that liquid crystal display elements such as PSA-VA, PSA-OCB, PS-IPS/FFS and PS-TN can be expected to achieve such effects by using a combination of a polymer and a polar compound in a liquid crystal display element without an alignment film by using a liquid crystal composition containing a polymer and a polar compound to control alignment of liquid crystal analysis, but LC mixtures and RMs have some drawbacks in application to IPS/FFS displays. For example, the panel process requires the application of alignment layers, which not only complicates the process and affects the throughput of the production line, but also results in the emission of organic contaminants, and in addition, n.a. Clark et al Langmuir2010,26 (22), 17482-17488 have described that the following structural compounds may be used: Self-assembly on a substrate to give a monolayer capable of being photoaligned to induce homeotropic alignment of liquid crystals. However, a separate step of self-assembly is required before the LC cell is fabricated, and disadvantages such as reversibility of alignment after exposure to light are reported.
