LCD is a type of TV. Then the top names are sony-panisonic-toshiba.. The reason LCD is better is the crisp pic it gives and the fact that it wont burn a image on your screen like a plasma would. So if you are a video gamer like myself LCD is the best.
LCD is Liquid Crystal so there is a actual liquid in the tv. Plasma is a gas based tv which also will fade away after time. Now the bad things about LCD.. Its a liquid.. It can and will freeze and if that does happen kiss the TV goodbye. Also the darker images are harder to see in some LCD TVs.. I had done much research and read all the stuff through consumer reports. I purchased my 52" LCD from Costco. They are a hard place to beat as far as prices..

Other than that good luck
