Cracked LCD screen

If it's old, it could use CCFL back lighting which has a small amount of mercury. I don't believe there's any in an LED based display.

You may have cracked it if you closed the top and there was something inside just a wee bit bigger than the gap between the screen and keyboard/mousepad.

If you can see the defect with the laptop turned off in a bright light on an angle, then the inside glass layer is cracked. These cracks do generally get worse. If it's a newish laptop, you can change the screen.

It'd be unusual if glass that was part of the display itself was cracked and it didn't seriously mess up the display, like large areas near the cracked not working much if at all.
