LCD busted (Help knowing what I did wrong!)

well it was working and I've tried it on both sides and all to try to make it work again but it doesn't. My other theory for why it messed up was I had it laying on top of the arduino board so I suspect that maybe one of the metals touched a part in arduino with really high voltage.... just a thought tho I really don't know where I messed up it was working I left for a while when I came back 5 minutes later... it was busted and wouldn't light up.
