^I would definitely not recommend that.
I'm going to say it one more time, just for my own satisfaction. I've worked on thousands of electronics with LCDs, seen plenty of cracks and plenty of water damage, and this looks like a crack.
If the picture shows what I think it does, which is the effected area is solid black, with absolutely no pixels visible in the damaged area, then it is irreversibly damaged. If an LCD is liquid damaged, the effected portion will become darker, but you can still see the image underneath it.
