present day LCD technology has come to so advance !!! Now LCD comes with more then 50000/1 dynamic ratio also panel comes with 100 Hz Technology.

Now LCD is way head of plazma. The link given in earlier answer is 2 years old!!! So it is LCD is better thats why SONY, SAMSUNG and other company makes Few Plazma TV compared to LCD.

Also a result of the success of LCDs, the number of plasma manufactures has decreased over the past two years. LCD is WAY AHEAD go for LCD or LED !!

So while no technology can be successful forever, plasma has at the very least a few years left, it won't be LCD that will kill it. The only technology that actually seems poised to replace it is OLED!!

GO FOR LCD
