In The Help, Davis plays a maid whose story becomes part of a book that tells of the experiences of African-Americans working for white families.
Some critics have expressed their displeasure at seeing black actresses playing the roles of maids once again.
"If what the African-American community wants, which is what I want, is a vast array of storylines on screen, then I think that they have a point," Davis told USA Today.
"I think that we want to see different people on screen other than the maids, other than the urban mother, other than the gang-banger. OK? So it's valid in that sense.
"But this movie still, regardless of all of that criticism, is a great story."
She added that it was "an honour" to be able to tell the stories of her mother and grandmother, who were both maids.
Davis, who is nominated in the 'Best Actress' category at the Oscars for The Help, also revealed what roles she would like to take on if given the chance.
"I've always wanted to be the black girl with an Afro in a John Ford movie, with the only backdrop being the land," she shared.
"I've always wanted to do sci-fi. I've always wanted to play some grand sweeping figure in history. And I've always wanted to create work for other actors of colour. For me, it's about passing on the baton."
