Lift the display up to a near-vertical position.
At this point there is still a strip of adhesive along the bottom of the display that will hold the display to the frame like a hinge. You can loosen this adhesive by working the display up and down a few times.

The adhesive strip along the bottom is designed with a pull tab on each outer end. Rather than lever and pull the screen simply carefully pull the tab which removes that half of the lower adhesive strip and frees up the screen.

Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply (boxed in red).
Grasp the small tab at the end of one of the bottom edge display adhesive strips and pull the adhesive toward the top of the iMac to remove it.
Repeat this step with the other adhesive strip and remove it.
If either adhesive strip breaks before it's removed, use a plastic card to slice through the remaining adhesive.

Vorsicht: Wenn man den Bildschirm einfach versucht vom Kleber wegzureissen, besteht die sehr grosse Gefahr, dass danach der Bildschirm tatsächlich defekt ist, was daran zu erkennen ist, dass dieser bei der Inbetriebnahme schwarze Diagonale Striche oder Lücken enthält. Dann muss der ganze Bildschirm ersetzt werden, was dann recht teuer wird!

Caution: If you simply try to tear the screen away from the adhesive, there is a very high risk that the screen will actually be defective, which can be seen from the fact that it contains black diagonal lines or gaps during commissioning. Then the whole screen has to be replaced, which then becomes quite expensive!

Lift the display up from the frame and remove it from the iMac.
It may be necessary to slowly lift from one side to peel against the remaining adhesive.
Be very careful handling the display—it's big, heavy, and made of glass.
After the adhesive is cut, it cannot be used to re-seal the display in place. Follow this guide to replace the adhesive strips that secure the display to the rear enclosure.
