Abstract
A liquid crystal display apparatus includes a liquid crystal display panel including a first substrate, a second substrate, and a liquid crystal layer and a plurality of pixels. The first substrate includes a first electrode provided in each of the pixels and a first horizontal alignment film that determines a pretilt orientation of a liquid crystal molecule. The second substrate includes a second electrode provided to face the first electrode and a second horizontal alignment film that determines the pretilt orientation of the liquid crystal molecule. Each of the first and second horizontal alignment films is a photoalignment film. At least one of the first substrate and the second substrate includes an anchoring structure in each of the pixels. The liquid crystal display panel further includes an alignment sustaining layer which is formed on the surface of each of the first and second horizontal alignment films on the liquid crystal layer side, is configured with a photopolymer, and imparts a pretilt angle greater than 0° to the liquid crystal molecules.
