A liquid crystal display device including 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 and second alignment films are both made of a photo-decomposition-type material. A film 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 a formula (1) and a formula (2): 0 nm
