They estimate a perfect LCD or plasma will last about 10 yrs.

Samsung claims that the plasma display of their units will last 60,000 hours
or approximately 26 years using it an average of 6 hours a day. It makes
sense to me given that the plasma pixel is simply a contained mini cell of
gas that becomes ionized when used. In the process of ionization light is
emitted. Once the ionizing potential is removed, the gas reverts back to
it's original state. There is no consumable component as long as the gas
does not leak out. Conventional cathode ray tubes emit electrons from a
filament that eventually will break or simply thin to a point of becoming
unusable.

Other components (power supplies, etc.) will crap out long before then.
