Marks on my Macbook Pro Retina's Screen

I was cleaning my macbook pro retina's display with Apple's piece of cleaning cloth that came with the macbook in box. But after I'm done cleaning I noticed weird marks on my screen and they won't be removed with cleaning liquids or even with pressure. they looks like if the black color of the screen frame was scratched .. but is that even possible ? since its already has a glass layer above it ?! So anyone know how are those marks appeared ? and how to remove them if possible ? I hope the images are clear enough
