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

I can't say how this evolves overtime, but I've seen a lot of units being sold with such defect, which can affect also the alphanumeric characters :



Storage conditions (temperature, humidity, pression, and variation of these) may play a role in how the defect appears and evolves. As the blackening starts on the edges and seems to move to the center of the screen this may be due to the sealing of the display glass panels degrading overtime. The Sharp grey LCDs are less impacted than the yellow ones but they are not totally immune.

You can see a collection of units pictures with more or less bad LCDs here and here, including a Sharp EL-5100S with a defective grey LCD.
