Work your way around the monitor, putting the flathead screwdriver into the space between the front and back covers, and prying up.
Twisting the screwdriver can help, but you can easily mess up the plastic without getting anything out of it by doing so. Be cautious.
Ideally you want to pry at the locations that have the little gaps, which are locking mechanisms.
You should hear a poping sound and the back cover should lift a little if you are prying at the right locations.

To remove, insert a Flathead screwdriver into the gap to push the locking mechanism back a little, while pulling up on the board.

Remove the bundled cable connector that is going to the top of the monitor. Grab the black tape that holds all the individual wires together, and pull gently.
Be careful to pull evenly on all the wires. You can do this by pulling strait out and not at an angle. Jiggling a little bit can help, but be careful.

Remove the bottom foil tape from the back of the LCD.
Be sure to keep it. It helps dissipate static to the ground while the screen is in use. I recommend leaving the side of the tape that is sticking to the shield, where it is.
