LCD: semiconductors emit light when excited
Plastma: gases emit light when excited

may also want to read up on how CRTs or televisions work before hand.

Plasma starts to leak after 8 years or so..

I hear most manfactures are moving toward LCD's now rather than plasma since I guess it is a better technology though I'm not sure.

That's correct for LED displays, but not LCD. LCDs use liquid crystals that selectively block the light from a backlight (usually fluorescent), as the article you linked to correctly describes.
