What I'm trying to determine is if it is just the adhesive or if the inside frame has broken. When they break it usually is on the left hand side about an inch up from the bottom. Yours may have broken which allows the display to flee and pulls the glass loose on the bottom. This may also just be a case of adhesive failure that can be fixed with a heat gun and some pressure. If you can post a couple of pictures if might help to determine the cause. Has the screen ever been replaced?
