Will an LCD last longer if you keep it at a lower brightness?

My LCD has a different setting for the backlight and the brightness... you should be worried about the former.

The best thing is to have the LCD go off whenever you are not using it. On a laptop, that is set in power management - for a separate desktop unit, just turn it off. Don't let it run with a screen saver. That just wastes part of its useful life.
i have the first Sony ones... an SDM-S81... and theyre pretty crappy compared to the ones out now... 
LCDs get noticably dimmer as they get used. If you aren't using it, turn it off.
I don't think the brightness will affect the life that much though. Not long enough to warrant having to have to use your nice LCD monitor as a sub-par setting.

Setting the monitor dimmer wont make it last longer.
The backlights are CCFLs, the same amount of stress gets put on it whether you have it on full blast or half way.

Having it go into powersave mode is sufficient for "powering off", yes? I have my screen set to go into screensaver mode after 10 minutes for 5 minutes and then DPMS off.
On the bright side, if a monitor does start going bad, you can squeeze every ounce of energy from it by cranking settings in drivers to make it look like it used to. Whilst saving for new ones of course
That depends on what brightness setting you're adjusting. I have a Sony that has a specific backlight intensity setting and I've verified that it adjusts the inverter power output setting. 100% is still the best setting!
Most monitors DO in fact run their inverters at full bore all the time. A blank screen saver is useless in this regard. However, powering off either with the power button on the front bezel OR through power management in your operating system will turn the inverter off and preserve the useful life of the tubes.
Either way, there is no reason why one cannot get three solid years out of a TFT and that's leaving the backlight ON 24/7.

Bah. I just let it do all the work. Just grab the mouse and the screen turns on. Get up and leave and the screen turns off after ten minutes of inactivity.
That way, if I get up for just a minute, and that "minute" turns out to be hours or all day, I know it will power down on it's own.
Of course, I know I'm wrong, but I tend to disagree. The manual for my Hp monitor which is now long gone said that the expected backlight lifetime is around 30K hours at 50% maximum brightness. It also warned against using it at maximum brightness for prolonged periods of time. So I guess brightness does affect lifetime.

Humbug! If you do that twice a day for 5 days in the week, that amounts to 100 minutes of burn time that is not necessary. In a month, that is at least 400 minutes - and in a year, 4800 minutes. That euqals 80 hours off the life of the monitor.
Peace!

Aaah yes, but that is Sony for you... Unless it is in the Pro-Video range I wouldn't buy a CRT from Sony nowadays at all. Their quality control is abismal when compared to just a few years ago.
The 21" CRT market is now firmly the domain of Mitsubishi and NEC IMO.
Back on topic:
I don't think you will notice the backlight going that quickly. Compared to a CRT an LCD will still be much brighter and more vibrant after the same use over a couple of years. Of course protecting your investment is always wise so just use the powersave function to prolong any screens usefull life.

You are forgetting the times you are called away for what you think is just a few minutes and it turns out to be hours or all day. You cannot deny this has happened to you more times than you like.

Ha, ha! That doesn't happen. No one calls me away. I am retired. If the wife calls me , I always just touch the LCD on/off switch - (skin contact only) and it is faster than any thing else.
