It used to be quite common for LCD displays to exhibit very rapid and
disturbing changes in displayed colors and brightness with changing
viewing angle, usually at different rates for horizontal shifts than
for vertical shifts.

When I purchased my LCD display a couple of years ago, I knew that I
would be using it for photo editing, so I made a point of finding a
display that had a relatively wide range of viewing angles for which
color and brightness were essentially constant.

Some laptops now have relatively wide viewing angles, while others
are rather narrow. Some business users even consider a laptop display
with a wide viewing angle to be a problem, since it allows people
sitting near them to read their screens! (A product has even been
introduced to create an artificially narrow viewing angle to deal
with this concern. ;-)

As more people use laptops for photo editing and for movie viewing
for more than one person, you can expect the typical laptop display
viewing angle to improve significantly.
