It looks like your LCD panel is going bad IMHO. Do you still have the same image when changing the screen resolution via ->system preferences -> monitors ?

To give you an adequate diagnostic we would need to know if you get (or not) the same image on an external monitor. Could you connect your MBP to an external ?

If the video is normal on the external monitor then the LCD panel or the LVDS (video) cable is not working as it should. You say <<...And i can make them disappear when i press on the surface of the MacBook...>> Do you mean the lines disappears when you apply pressure on the LCD display or on the MBP case ? If it's on the LCD display then it can indicate a LCD electronic board failure. If it's on the case then the problem could be caused by a bad LVDS cable connection to the logic board or a faulty GPU (graphic processor unit).
