LED display design

I need to build a sign. It will have 7 letters and I want to use LED's
to backlight it. I'm going to need to light about 40 of them. I have
tinkered around with LED's in the past and I have a basic knowledge,
but I thought I'd ask others for thier opinion before I spend all of
this time and money.
This circuit needs to be powered by 110 VAC. The LED's are 3.6v @ 20mA.
Should I use a lower voltage power supply? Are there schematics for
projects like this on the web that might come close to what I'm doing?
Series or paralell?
Help!
