Because we're not removing the top half of the computer from the bottom half, you'll need some temporary fancy-footwork here:

Pull back on the LCD enough to the point that you can unscrew all 3 screws from the right side, as well as the 3 screws from the left side.

Once you have enough leverage to remove the bottom screw from the LCD bracket, you have pulled far enough. It has some give, but try not to stress it beyond this point.
