FIG. 1.

(Color online) (a) Adding C3 to LC1 leads to the loss of vertical alignment. (b) Adding 5CB to the C3-LC1 system helps to obtain vertical alignment. (c) Critical amount of 5CB as a function of the concentration of C3.

FIG. 2.

(Color online) Liquid crystal mixtures capable of producing uniform vertical alignment with (a) greater negative dielectric anisotropy and (b) greater birefringence

Image of FIG. 3.
FIG. 3.

(Color online) Mixture with 10% C3 and 2% 5CB shows better performance than pure LC1. (a) Electro-optical curve shows that the improved liquid crystal mixture has lower driving voltages and higher birefringence. (b) Improved liquid crystal mixture shows similar response time to LC1.

Image of FIG. 4.
FIG. 4.

(Color online) In the mixture of LC2 and 5CB, increasing the concentration of 5CB causes the alignment transitions on SiOx, from planar to vertical then back to planar again. (a) Pretilt angle (from substrate surface) as a function of 5CB concentration. (b) Cells observed between two crossed polarizers. Vertically aligned cells look dark and planar cells look bright. From the top left to top right: 5CB, , . From the bottom left to bottom right: , , LC2

Tables

Table I.

Alignment of mixtures composed of a high negative host LC and dopants similar to 5CB in different aspects. “NUP” and “UP” stand for nonuniform planar and uniform planar, respectively. “UVA” stands for uniform vertical alignment.
