Hi zara
the main problem with lcd over tft screens is they are
fragile ,however the lcd screens have a better visual reproduction
the problem with your screen looks like the screen has cracked and some of the solution thats in a lcd screen(remember lcd means luquid crystal display)has leaked and this is whats causing the problem
two options open to you....................
1)all laptops have a vga-out socket at the back of the laptop,using this you can use a cheap ldc/tft monitor,infact you could even use a c.r.t monitor,at least you would have a working display
2)contact a laptop/pc screen repair center such as trafalgar electronics at http://www.trafalgarelectronics.co.uk/,they can repair your screen,however be warned,fixing a laptop screen is a expensive repair and its sometimes costs as much as a new laptop,so shop around
nice
luck zara !
