None of the liquid sensors have activated so i assume it was a very small amount but this needs noted. Overall I would say this screen is in good condition (probably a 7/8 out of 10) with some minor scratches and the liquid part at the bottom.
I do not know for sure. See pics to show it is fully functional and original Apple.
