[Elecraft] Question on LCD backlight assembly

[NZ8J]

On page 26 of the assembly manual, the 6th step down, it says do not remove
the backing from either side of the diffuser, I assume that means to leave
the paper backing on that has the writing on it?

Also, I don't thing there is a protective film on the back of the LCD, I do
not see any faint yellow or gray  diagonal lines. Would there be any film on
it without the diagonal lines?

Thanks
