I don't think alcohol will dissolve super glue. Finger nail polish remover may work, although it contains acetone, it is diluted, otherwise it would literally dry the skin out on the fingers.
You might be able to shave it off with a sharp knife. Don't cut the screen, just the glue. Kind of like shaving..Super Glue is funny, the thinner the layer the better the bond, so it should not be set really hard on the screen. If it isn't set in to hard, you might be able to remove it with your finger nail or guitar pick.. just something hard enough to dislodge the glue without scratching the screen. It might sound a bit odd, but it worked on 8 microwaves, 3 stoves, 2 refrigerators 12 tables and 30 feet of counter top and 2 stainless steel sinks.
It seems, telling a student painter to "cover everything" 6 times and a box of 20 tarps wasn't enough. LOL
