Just figured it out while replacing my LCD cover. When you have the screen separated from the body (and the hinge cover in the middle taken off as well), you need to hold the LCD cover (the back) steady, and slide the front with the screen downwards. You should see a little gap form and stay at the top between the cover and the screen now. After that, just apply a little upward pressure from the bottom in one of the sturdier spots between the screw holes, and the LCD should come up.
