Yes, very true (although a good CRT will last a VERY long time). I am
basically curious about any long term chemistry that might occur. I can
see the rubber contacts on most LCDs failing in time, but they could be
replaced. What about the actual "liquid"?

Yes, EL panels have half-lives, just like radioactive isotopes.

About the only backlight that will not fail are the woven fibre optic
sheets, but they are very expensive, and probably not used on anyone's
