摘要：
A liquid crystal display apparatus having a pair of substrates with a liquid crystal layer interposed therebetween is disclosed. Also, a method for producing the same and a substrate are disclosed. 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, and the degrees of roughness are different among a plurality of prescribed regions.
