Trying to repair an OG Droid

So I purchased an old Droid from ebay for like 30 bucks. It needs some work though.
I went ahead and bought this replacement digitizer for it:
Digitizer LCD Glass Display Touch Screen Replacement for Motorola Droid A855 | eBay

Because the right side of the screen does not detect my touch.
I just was wondering if you can tell whether there's adhesive on this digitizer or not.
It looks like there's a film on the backside of it that peels back that covers adhesive that they put on it, but it's hard to tell
by the pictures and description if that's what you're supposed to do with it. Can anyone tell? Thanks.
