To model a LCD more correctly, I guess you may take into account
the effect that two polarizing layers (90 deg on each other) some
distance apart, has on the light.

Light falling in from different angles seems to be blocked differently.

On some LCD one can also see a weak shades of digits that are not
turned on if one tilt the LCD slightly.

You may also model the different layers of glass and liquid crystal that
are inside these.

By the way: Is it possible to model polarizing filters in POV-ray?
