My husband does not interact with my daughter that much and is always watching TV. how do I explain her that it is important for him to spend time with her as well?

I agree with what Debolina suggested. Get the family out of the house. Go to the playground. Perhaps your husband can teach your daughter something, cycling or swimming or some sports (not sure what your husband and daughter may enjoy). Anyway, can also highlight the fact the lack of communication to your husband. He may not realize that he has not been actively engaging your daughter.
