Liquid crystal display device and manufacturing method thereof

A liquid crystal display device comprising:

• a liquid crystal display element including
• a first alignment film and a second alignment film that are provided on opposing face sides of a pair of substrates and
• a liquid crystal layer that is provided between the first alignment film and the second alignment film and that includes liquid crystal molecules with negative dielectric constant anisotropy,
• wherein the first alignment film includes a compound in which a polymer compound that includes a photosensitive functional group as a side chain is deformed,
• the second alignment film includes a same compound as the compound that configures the first alignment film, and
• a formation and processing of the second alignment film is different from a formation and processing of the first alignment film and when a pretilt angle of the liquid crystal molecules which is conferred by the first alignment film is θ1 and a pretilt angle of the liquid crystal molecules which is conferred by the second alignment film is θ2, θ1>θ2.

A manufacturing method of a liquid crystal display device comprising:

• performing formation and processing of a first alignment film composed of a polymer compound that includes a cross-linked functional group or a polymerized functional group as a side chain on one of a pair of substrates and performing formation and processing of a second alignment film composed of a same polymer compound as the polymer compound that configures the first alignment film on the other of the pair of substrates;
• arranging the pair of substrates so that the first alignment film and the second alignment film are opposing and sealing a liquid crystal layer that includes liquid crystal molecules with negative dielectric constant anisotropy between the first alignment film and the second alignment film;
• and
• conferring a pretilt on the liquid crystal molecules by cross-linking or polymerizing the polymer compound,
• wherein the formation and processing of the second alignment film is different from the formation and processing of the first alignment film, and when a pretilt angle of the liquid crystal molecules which is conferred by the first alignment film is θ1 and a pretilt angle of the liquid crystal molecules which is conferred by the second alignment film is θ2, θ1>θ2.
