“…Figure 3. When this plot is compared with previous published data [4], it is found that LCDs which have twists of 70°, 80°, and 90° and ∆nd values of 0.275, 0.26, and 0.24 µm, respectively, have decreasing brightness which is seen above, marked by dots. LCD is not nearly as good as that of the 70°, 80°, or 90°, therefore the 100° twist cell is not normally used for displays.…”
