Backlight screen material

I have a 13" Macbook Air on which I replaced the faulty screen. Unfortunately the backlight material got bent and gives a distorted video output.

There are 3 layers/sheets of material behind the screen but the one directly behind the screen is the only one that got bent. Does anyone know where I could purchase this backlight material? It looks like a thin grey mylar sheet. I have tried smoothing it out with no luck.

Any suggestion greatly appreciated.

Thanks in advance.
