Abstract
A liquid crystal display device includes a first substrate, a first alignment film formed over the first substrate, a second substrate, a second alignment film formed over the second substrate, a liquid crystal layer sandwiched between the first alignment film and the second alignment film, and a projecting portion formed over the second substrate. The first alignment film is a photo alignment film, and a thickness “d2” of the second alignment film over the projecting portion and a film thickness “d1” of a portion of the first alignment film facing the projecting portion satisfy formula (1) and (2):0 nm<d2<30 nm (1);d2<d1 (2).
