So, don’t ask how or why, but how resistant is a soft LCD screen (laptop) to lemon/lime juice? (as opposed to a hard LCD screen, like that of a smartphone)

The top layer or an LCD is generally plastic or glass, and will resist most liquids other than strong acids, bases or solvents.  
Lemon juice is no problem.

On the other hand, if the edge got wetted, then some might seep around behind the impervious top layer, and corrode or short electronics.

Yeah, if it’s just spots, it shouldn’t damage the screen at all - you’re more likely to cause damage in the process of wiping it off (if for example you use a rough or dirty cloth)
