That's a broken LCD. See another one grow.

That is a leak of the liquid crystal, possibly due to freezing or a direct impact. I actually got to witness this effect as it grew and spread over time in the display of an HP 200LX palmtop. There is an animated gif (link below) of the process recorded over 9 days through a USB microscope at about 10x magnification.
