There is no difference.
Okay, technically there is, but since copyleft is really just a subset of copyright, I don't see the question as a valid one.
Copyright laws protect an artistic work from unauthorized reproduction or sale. Copyleft licenses are legal contracts between the creator and the user. They often stipulate that users may reproduce any part (or even the whole) of the work for their own use, so long as they give credit to the original creator. If they don't, presumably, the creator can sue.
So a copyleft license is a legal contract between artist and consumer, which is protected by the larger set of copyright laws.
