You should make a Genius Bar appointment and go into the Apple Store. They can help you there.
If you have an Apple-owned store available, your appointment for an evaluation is free, in warranty or out. The technician will evaluate your computer and do what he can in about a quarter hour to "make it go".
If the technicain's activities do not involve swapping parts, there is generally no charge. (For example, you may have a partially-disconnected display cable, and they would look for that and re-plug it in.)
If parts-swapping is required, and parts are still available, they will tell you what Apple will charge for the service -- fixed price, no surprises.
As y_p_w says, for Macs older than about three years, parts may no longer be available, but you should still be able to get the evaluation and ask questions.
Your time with the technician is not exclusive -- they may be helping another User with a long process (such as a re-Install) on the side. As long as they feel your visit is being productive, they will continue to work with you.
Apple wants you to be a happy customer, IF POSSIBLE. People who threaten to sue every one and are not calm and professional will never be happy customers, so their visits may be terminated.
That doesn't look good. What model? I can't tell but it looks like a Unibody MacBook.
If it's past a certain vintage, Apple won't service it, although you could try asking if they could at least evaluate it for advice on what the next step is. It doesn't look like physical damage to the display, but it could be a connector that was jarred loose. There are instructions on how to remove a display, which you could use if you're adventurous enough to look into it yourself. I'm not saying you have to remove it, but such instructions should get you as far as where the display connector is.

That's plenty of information. There should be a model number on the bottom and a serial number too. You can look up the exact info in Apple's serial number support check:
Check Your Service and Support Coverage - Apple Support
But mostly it was about how old it is, and anything that recent is supported with parts by Apple. If you're close enough to an Apple Store, they should be able to evaluate it for free. And as stated, if it doesn't require any part then Apple will likely fix it for free.

Did I break my MacBook?
