ABSTRACT:
The liquid crystal display apparatus of the invention includes a first substrate and a second substrate disposed so as to face each other, a liquid crystal layer sandwiched between the first substrate and the second substrate, a first alignment film formed between the liquid crystal layer and theist substrate, and a second alignment film formed between the liquid crystal layer and the second substrate. In the liquid crystal display apparatus, the liquid crystal layer includes a plurality of liquid crystal layer regions having aligning conditions which are different from each other, the plurality of liquid crystal layer regions including a first liquid crystal layer region and a second liquid crystal layer region, and wherein the orientation direction in a substrate plane of liquid crystal molecules in the vicinity of the center of the first liquid crystal layer region is different from the orientation direction in the substrate plane of liquid crystal molecules in the vicinity of the center of the second liquid crystal layer region, substantially by 90.degree..
