    That's the diffuser peeling away from the LCD panel. You're seeing the backlight LEDs.

    It's a hardware problem with the LCD panel. Might be repairable else hope it's under warranty.

    Since it's a defect you might want to take it to an Apple Genius first.

    i dont have applecare, i bought it from ebay a few weeks ago.

    i just looked on youtube and a guy pressed SHIFT, CONTROL and EJECT buttons and the screen goes black then it goes back to normal screen without the lines. i tried it and now the lines have gone but everytime i switch on the laptop i see the lines and have to do the same again :(

    It's clearly the backlight, which normally is a hardware problem, what is odd though is you say it's gone when you press those keys, have you tried to reset the PRAM and SMC?

    How about reading them, if I explain to you here which I could do it will say exactly the same as in the links.

    For the PRAM reset I can say here because it's the same all all Macs.
    PRAM reset, Hold Command-Option-P-R all at once at startup, keep them pressed until after the 2th or 3rd startup sound, then release them, the mac will boot normally.

    About the SMC reset it depends on the model, if you have a removable battery or not so read it yourself.
    But for your convenience I pasted part of that page here.

    According to this site, you can try the key combination of Shift+control+Eject to put the display to sleep, and on wake the issue should be gone.

    LED backlight driver board is dying, it looks like half the LED's in the strip are not lighting.

    It's a inexpensive part, but you have to take apart half the laptop and the screen to get to it.

    Can't fix a broken LED diffuser with software. It's a hardware problem, could be when the screen's off the diffuser moves but it's still not something fixable in software.
