Abstract:
A liquid crystal display device includes a liquid crystal display element including a first alignment film and a second alignment film and a liquid crystal layer that is provided between the first alignment film and the second alignment film, wherein the first alignment film includes a compound in which a polymer compound that includes a cross-linked functional group or a polymerized functional group as a side chain is cross-linked or polymerized, the second alignment film includes the same compound as the compound that configures the first alignment film, and 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.
