Plasma and LCD panels may look similar, but the flat screen and thin profile is where the similarities end. Plasma screens, as its name suggests, uses a matrix of tiny gas plasma cells charged by precise electrical voltages to create a picture. LCD screens (liquid crystal display) are in layman's terms sandwiches made up of liquid crystal pushed in the space between two glass plates. Images are created by varying the amount electrical charge applied to the crystals. Each technology has its strengths and weaknesses.
What advantages does plasma have over LCD?
Apart from better contrast due to its ability to show deeper blacks, plasma screens typically have better viewing angles than LCD. Viewing angles are how far you can sit on either side of a screen before the picture's quality is affected. You tend to see some brightness and colour shift when you're on too far of an angle with LCDs, while a plasma's picture remains fairly solid. This is steadily changing, however, with more and more LCDs entering the market with viewing angles equal to or greater than some plasmas. Plasmas can also produce a brighter colour, once again due to light leakage on an LCD affecting its colour saturation.
Plasma pundits will also tell you that some LCD screens have a tendency to blur images, particularly during fast moving scenes in movies or in sports. While that was true for older generation LCD screens, newer models have improved significantly - so much so that the differences in performance between LCDs and plasmas in this regard is almost negligible (here's a tip -- if you're shopping for LCDs, check the refresh rate. The lower it is, the better the image quality in fast moving scenes).
Perhaps the biggest advantage plasmas have now over their LCD cousins is price, particularly in the large screen end of the market. Plasmas typically come in larger sizes than LCDs at a cheaper price.
What advantages does LCD have over plasma?
It's not all doom and gloom for LCD though, as it has the edge over plasma in several key areas. LCDs tend to have higher native resolution than plasmas of similar size, which means more pixels on a screen. If you're a true high-def junkie who's keen to see every pixel of a high-res 1080i/p image reproduced pixel-by-pixel (providing you have a source that high, of course), then LCDs are the way to go.
LCDs also tend to consume less power than plasma screens, with some estimates ranging that power saving at up to 30 per cent less than plasma. LCDs are also generally lighter than similar sized plasmas, making it easier to move around or wall mount.
LCD pundits also point to the fact that LCDs have a longer lifespan than plasma screens. This was true of earlier plasma models, which would lose half of their brightness after more than 20,000 hours of viewing. Later plasma generations have bumped that up to anything between 30,000 and 60,000 hours. LCDs, on the other hand, are guaranteed for 60,000 hours.
You might have also heard that plasmas suffer from screen burn in, an affliction not as commonly associated with LCDs. Screen burn in occurs when an image is left too long on a screen, resulting in a ghost of that image burned in permanently. Newer plasmas are less susceptible to this thanks to improved technology and other features such built-in screen savers, but we still hear anecdotal reports here of burn-in with new plasmas.

Lcd's last longer, and there made from a liquid crystal display. Plasmas use special components to operate them

great answer panther, in addition (i have both) a lcd works a little better for you in a sunny well lite room during the daytime
