No.

Actually, it IS possible - IF the monitor is stored in such
a way as to result in pressure being applied to the LCD panel
itself, especially if this pressure is applied to a small point or
area. The potential problem comes from losing the proper
spacing or "cell gap" between the front and rear glass in the
panel, which can result in brightness and/or color uniformity
problems or other artifacts (look up "mura," which is often
used as a generic term for this class of problem).

The monitor, of course, should never be OPERATED in
any but the expected normal orientation(s), due to possible
thermal issues.

No, but experience with customer problems in this regard
suggests that such damage is MUCH more likely if the
monitor is "laid down" such that it is resting on its front
surface. Hence this added caveat with respect to the original
poster's question.
