If you don't see these lines on an external monitor connected to your MB, if the lines don't change location when opening or closing the lid then your LCD panel is probably faulty and you'll need to replace it.
To identify your LCD panel model: open your application Terminal located in Applications -> Utilities, copy this string:
ioreg -lw0 | grep IODisplayEDID | sed "/[^<]*</s///" | xxd -p -r | strings -6
paste it in the Terminal window and press return. This will tell you your LCD panel model. Using this info do a search on the web for a replacement panel. Check this link to know how to swap the LCD panel:
