What is wrong with my screen?

Hello. Please, will someone help me to understand what is going on?
At first, small amount of this thing was around the camera. Now it is spreading more. Also, it is in bottom left corner now.
Hope to prevent this? What to do?
Thanks

it's a known problem - https://www.macrumors.com/2017/02/24/apple-extended-anti-reflective-repair-program/

Screen delamination, the anti-glare coating is coming off. I had mine repaired for free.

You have "StainGate".

As robvas wrote above, "the solution" is to take it to a brick-n-mortar Apple Store genius bar.

Chances are, they're going to replace the display, free of charge.

But, DON'T POSTPONE THIS. Get it done right away!
