Abstract:
A liquid crystal display device includes: a first polarizing plate; a first substrate; a first vertical alignment film; a liquid crystal layer; a second vertical alignment film; a second substrate; and a second polarizing plate, wherein a first retardation layer is disposed between the first polarizing plate and the liquid crystal layer and includes first and second areas having mutually different in-plane phase differences, a second retardation layer is disposed between the second polarizing plate and the liquid crystal layer and includes third and fourth areas having mutually different in-plane phase differences, the first and third areas overlap boundaries between at least four domains of liquid crystal molecules in a pixel region and have an in-plane phase difference in a predetermined range, and in-plane slow axes of the first and third areas and absorption axes of the first and second polarizing plates each have a predetermined azimuth.
