A liquid crystal display apparatus includes a pair of substrates with a liquid crystal layer interposed therebetween. In the liquid crystal display apparatus, an aligning film is formed on at least one of the pair of substrates. The surface of the aligning film is made rough for controlling pretilt angles of liquid crystal molecules in the liquid crystal layer which are in contact with the surface of the aligning film. Further, the degrees of roughness are different among a plurality of prescribed regions.
