At the present time, all laptop screen displays are manufactured using very thin layers of glass that are sandwiched together. Between these layers of glass lay the liquid crystals that make up the "pixels" of the display.
Pressure around the corners of the screen causing any slight "bending" of the laptop screen panel, or pressure on the surface of the screen can crack these layers of glass and sometimes cause the liquid crystals to leak, as in the example image to the left.
If the laptop has been involved in some kind of impact, (such as being dropped), or any other kind of shock, it is a sensible idea to ensure the problem is related only to the LCD screen itself.
Connect an external monitor to your laptop and test the machines keyboard, hard disk drive and CD/DVD drives. If all looks and sounds okay it is more than likely that the problem is related only to the laptop screen itself.
