Using your fingers and a spudger, or any other opening tool, pry the bezel away from the display enclosure. First start from one of the two top corners and go along the long edge. Do not push the opening tool too much inside, its tip is already enough to disengage the tabs of the bezel.

Once the top edge is disconnected, disengage the short edges of the bezel, one at a time.

Leave then the bottom edge still connected to the display panel as it is shown in pic#3.
