Plasma panels give off image by using certain gases inside special cells and LCD panels give off image by modulating liquid crystals
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.
LCD are little lights for each and every pixel, while plasma has two pieces of glass with plasma between the two.
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.

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.
They dpon't make LED screens yet just LCD and plasma screens.
The difference between the two TVs is the high definition resolutions. There are many different companies that make both models.
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.
A plasma television has a higher picture quality over a larger sized screen, and better colour definition, especially deeper blacks. There is also less lag on moving images, and it can be viewed from wider angles.
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.
There are major differences between Sony's LCD and plasma TVs. A LCD TV presents in 4:3 ration, while a plasma presents in widescreen. Plasma TVs smallest size is 37 inches, while LCD are available in much smaller sizes. LCD TVs actually look better than a plasma screen when viewed center on, but plasma TVs can be view from multipe angle without picture distortion. LCD TVs, however, a better in rooms with a lot of light than plasma TVs. The decision will depend on your needs, preferences and budget.
