The RF shield that you are about to remove will be damaged in the process. you may be able to bend it back into shape once you remove it.

Locate the point where the display is still attached to the motherboard.

Use a flat spudger to pry off the RF shielding/bracket retainer.

Use a thin guitar pick to release the snap pin from the display to the motherboard.

The little black piece (the latch for the ZIF connector) that you have just flipped up is no longer held in place by anything due to Microsoft trying to make the device slimmer. It will fall out and be lost for all eternity unless you carefully keep track of it.
