Liquid crystal display
View Patent ↗The invention relates to a liquid crystal display based on an MVA mode of multi-division alignment in which alignment states of liquid crystal molecules having a negative dielectric anisotropy are made different from each other, and provides a liquid crystal display in which a drop in transmittance is suppressed and response characteristics are improved. The liquid crystal display is constructed so as to include a pair of substrates having a predetermined cell gap and arranged opposite to each other, vertical alignment films formed between the pair of substrates, a liquid crystal layer sealed between the vertical alignment films and having a negative dielectric anisotropy, an alignment regulating structural member arranged on at least one of the pair of substrates, for regulating a total alignment direction of liquid crystal molecules in the liquid crystal layer at a time of voltage application, and a cured material provided in the liquid crystal layer and including a liquid crystal skeleton for tilting the liquid crystal molecules.
1. A liquid crystal display comprising:
a pair of substrates having a predetermined cell gap and arranged opposite to each other;
vertical alignment films formed between the pair of substrates;
a liquid crystal layer sealed between the vertical alignment films and having a negative dielectric anisotropy;
an alignment regulating structural member arranged on at least one of the pair of substrates, for regulating a total alignment direction of liquid crystal molecules in the liquid crystal layer at a time of voltage application; and
a cured material provided in the liquid crystal layer and including a liquid crystal skeleton formed in a state where the skeleton is tilted to the substrate for tilting the liquid crystal molecules.
2. A liquid crystal display according to claim 1 , wherein when a tilt angle of one of the liquid crystal molecules on the alignment regulating structural member is θ pr , and the cured material includes the liquid crystal skeleton satisfying 0°≦θ pr <45°.
3. A liquid crystal display according to claim 1 , further comprising an alignment regulating structural sub-member for tilting the liquid crystal molecules substantially parallel to each other in an extending direction of the sub-member.
4. A liquid crystal display according to claim 1 , wherein the cured material is formed by polymerization of a photo-curing or thermosetting monomer.
5. A liquid crystal display according to claim 4 , wherein a concentration of the monomer is 0.1 to 3 wt %.
