Technically they're both LCD.  The difference is the backlighting: If LED is used as the light source, they refer to it as an LED monitor, but the actual display panel is still LCD.  If the monitor is described strictly as LCD, it has flourescent backlighting, not LED.  

"LED" monitors are mostly a misleading marketing thing, although using LEDs for the light source does have certain advantages over flourescent light source.  But either way, the actual display panel itself is LCD.

LED monitors have better contrast, resolution, color, clarity and are better for viewing at angles but cost more so it depends whether you are willing to pay a bit more for the better quality image

As IT-Monkey-Dave noted, all of the displays marketed as "LED" are actually LCD screens that use LEDs as the backlighting source rather than small fluorescent tubes.   There are a few displays with "full array" LED backlights -- which mean the LEDs are actually behind the display ... but the vast majority have the LEDs along the sides -- the same position that flourescent tubes are placed in more traditional LCD monitors.

Depending on the number of LEDs and their placement, LED-lit displays can have slightly better contrast than fluorescent lit units;  and usually have a bit less "bloom"  (bleed through at the edges.     But the key difference is the long term reliability.    Fluorescent tubes burn out ... and need to be replaced after a few thousand hours.    LEDs have a far longer lifespan ... they simply aren't likely to ever need replacement.

Given the very nominal price difference these days, I'd go with an LED-lit unit.

LED monitors will also consume about 40% less power - which is worthwile with larger sized ones (TV's)
