The thin outer layer of plastic has nothing to do with it, the screen is smashed - and from the picture there's a fairly obvious impact point at the bottom left corner - I would suggest the set has been dropped on that corner.
I spent over 46 years repairing TV's, including LCD in the later years - the screen is smashed, it's scrap.
The only value of the set is taking the PCB's out and selling them on Ebay - however, while you might think the boards are OK (because the screen is smashed) a common insurance fiddle is to drop the set (smashing the screen) and claim on your household insurance, when the set was faulty in the first place (a duff board?). So the boards aren't always OK from smashed sets.
