What is the difference between "CRT" and "LCD"?

The CRT or cathode ray-tube monitor is the old style big television looking behemoth that sits on your desk. The LCD liquid crystal displays are the new flat panels. A lot less energy used on the LCDs, less desk space, less power consumption, and overall now the quality of the LCD has gotten so good that it rivals CRT monitors. So, everything right now seems to be transitioning toward LCDs and the CRTs are pretty much gone. Except for some graphic design use you really don't see CRTs anymore.
