Does Turning on and off an LCD monitor harm it?

Question

I set my windows to shut down my monitor if i don't use my computer more than 5 mins (check out LocalCooling.com - It's a neat small software and you will realize why i did that)
As a result my Monitor turns off and on many times during the day (maybe 15 times or more) when i step away from my computer.
So i want to know if doing so will shorten my LCD monitor lifespan or harm it in anyways. I remember my mom used to always tell me as a kid not to repeatedly shut off and on our Sony 10 year old CRT TV all the time cause it reduces the lifetime of its light bulb. Is the same true about LCD monitors or TVs?

Cheers,

Let me just clarify this point that I don't physically turn my monitor off. Windows does it by putting it in Standby mode. So the light on the monitor turns Orange for being standby as opposed to Green which is for Active mode. So i can rephrase the question as:
"Does Putting my monitor on standby all the time harm it? (More than 15 times a day)"

Answer 1

I don't think it will harm it, unless you turn that monitor on and off every few seconds or so. Actually, turning ANY electronic device on and off too often is bad for it, in general.

Answer 2

I guess there different ideas. I never turn mine off, except during a Thunderstorm when I unplug everything.
The light will turn yellow and it sit in a stand by mode waiting for a signal (Best to explain).
When I boot the computer it fires up without me having to push another button and the light turn green (For Go).
