The difference is in the backlight and resolution. LCD usually have better resolution.
The difference between a plasma and widescreen lcd tv is that a plasma has less of a viewing range. They both have great video quality.
A JVC plasma is a brand of television and a plasma television does not use liquid crystal displays (which is and LCD television). Plasma televisions are thinner and provide crisper images.
Viewing angles for a plasma will not have as many problems as viewing angles for LCD's, Screen Refresh Rates / Pixel response time for plasma screens are faster, and plasma tvs tend to be heavier.

Plasma TVs use highly heated gases for the picture. LCD use liquid crystal displays. That's the scientific difference. As for the difference you will see, that's up to your eye and your opinion.
LCD is lighter than Plasma but plasma has a more true black color. Besides price you won't likely notice much difference. Earlier lcd models had trouble showing a true black, but the technology has improved considerably. There still is some difference, but it really comes down to weight and price now.
The difference between plasma and lcd TV is the type of material that is used to project the image. LCD has a good image but plasma has a better image. The only problem with plasma is that there is a greater chance of burning an image into the screen from overuse. LCD screens emit no light of their own, they need to be back lit by flourescent tubes or White LED's. They are cheaper to make, reasonably robust and lighter than a Plasma. Plasma screens are expensive, delicate, heavy, run hot, use lots of power, made of glass and emit their own light via the plasma trapped in individual cells. Plasma's used to have the better light output and definition, but LCD technology is fast catching up.
LCD are little lights for each and every pixel, while plasma has two pieces of glass with plasma between the two.
LCD's (liquid crystal display) tend to have a higher resolution, are lighter, and use less power than plasma screens. However, plasma screens allow for better viewing angles.
Plasma panels give off image by using certain gases inside special cells and LCD panels give off image by modulating liquid crystals
No because the LCD or plasma technology is relatively new. It also depends on the maufacturer. Panasonics plasma tv has a 100,000 lifespan versus 60,000 of an LCD. Plasma and LCD are not the same type of tv either.
plasma get hotter then LCD or led and plasma has some gasses in it
Plasma typically has deeper black levels and handles fast motion better. LCD uses less power, runs cooler and is better in rooms with more ambient lighting.
