Hey,
Well, I'll just list some pros and cons(compared to CRTs) of LCD, which will cover up your doubts too:
Pros:
Power- LCD requires about 1/3rd of the power a CRT requires for the same screen area. This lowers its heat generation too.
Runtime- An LCD will run well for about 40,000 hours, after which its backlight starts fading. A CRT will rune for about 20,000 hours after which it's brightness starts reducing.
Flicker- There is no flicker(refresh rate) in an LCD, so it's better for the eyes.
Geometry- An LCD can display perfect geometry, i.e perfectly straight edges. Whereas, a CRT normally has rounded edges.
Physical Size- An LCD is a fraction of the size of a CRT, thus looks good and saves space.
Cons:
Resolution- One of the major drawbacks of an LCD is that it has a fixed native resolution. If you change it's resolution from the native resolution, picture quality will suffer.
Viewing Angles- LCDs have narrow viewing angles(Especially from top to bottom). But the newer LCDs have quite wide viewing angles so this problem is being rectified.
So, that sums it up. LCDs are a bit expensive, but in the long run, they prove cheaper and eco-friendly.
Hope i helped!

Thanks for mentioning about fixed resolution. I have read this in a tech magazine and thanks to you I've remembered it now. But having a fixed resolution bothers me, some apps run at less than 1024x768 dpi.

Happy to help!:)
Well, using a different resolution deterioirates the quality but it's not THAT bad. I used to play a game(Sid Meier's Pirates) on 1024x768 whereas my LCD's resolution is 1280x800. The colours and geometry seems a bit washed out but it's ok once you get used to it. Also, there's an option in Nvidia graphics cards to shrink the screen for lower resolutions and display it in optimum quality(with reduced screen size).
Hope I helped!

LCD monitors consume far less power than CRT monitors, the cost of an LCD actually is less in the long run compared to their predecessor CRT type. A 17 inch LCD consume around 35W or less while a 17' CRT ranges from 80-90W(http://www.dssw.co.uk/research/computer_energy_consumption.html)
