Well, I happen to own a Sharp PC-1211 in that condition (in fact a pic of it would very accurately match the one you posted) but it's still perfectly workable.
The blackening affects only the part of the display external to the dot-matrix alphanumeric characters which still remain perfectly visible when the machine is turned on.

It's certainly a cosmetic nuissance but it does not render the calculator utterly unusable, it works Ok regardless.

AND (a very important AND) this has only happened to one of my SHARP PC-1211, which already came in that condition when I got it. The rest of my yellow-LCD PC-1211 are still perfectly fine with no blackening at all despite being some 38 years old, give or take a year. The grey-LCD ones (PC-1212) are all perfectly Ok, never seen one with a blackened display.
