Abstract
This investigation reports the optical simulation of axially
symmetric vertically aligned liquid crystal displays (ASVA LCDs).
The circularly symmetric iso-light leakage and iso-transmittance
contours of one subpixel result in the circularly symmetric
iso-contrast contours. The contrast ratio of the area close to <i>x</i>-
and <i>y</i>-axes at a polar angle of around 30° exceeds 10. The LCs near
some azimuthal angles are not perfectly aligned in circularly
symmetric manner because of the square subpixel. Such a reason
causes major reduction of the light utilization efficiency.
Additionally, the circularly symmetric iso-contrast has potential
for fabricating private mobile products.
