Abstract
A liquid crystal display apparatus of the invention includes a pair of substrates and a liquid crystal layer sandwiched between the pair of substrates with alignment films formed at interfaces between the liquid crystal layer and the respective substrates. The alignment films regulate aligning conditions of liquid crystal in the liquid crystal layer. In the liquid crystal display apparatus, the liquid crystal layer includes two or more liquid crystal layer regions of different aligning conditions, and at least one of the alignment films has surface tensions which are different from each other in surface regions thereof corresponding to the respective liquid crystal layer regions of different aligning conditions.
