That's some pretty awful backlight bleeding there. You can try 'rubbing it out' with an antistatic cloth. With a firm hand, stroke the screen from the edge to the centre wherever there's bleeding. It *does* actually work in some cases. If you can't rub it out, I'd say return it. I just returned three Samsung 930B LCDs in a row because of backlight bleeding, and it was far less severe than what your picture shows.
