Abstract
A display device includes a first substrate, a second substrate, a first polarization element film which is directly formed on a surface of the second substrate on a side opposite to a side where the first substrate is arranged, and a first polarization layer which is formed in contact with a surface of the first polarization element film on a side opposite to a side where the second substrate is arranged. The first polarization element film is made of an aligned lyotropic liquid crystal material, and the first protective layer is made of a material having a refractive index smaller than a refractive index of the first polarization element film in a transmission axis direction, and has a thickness smaller than a thickness of the first polarization element film.
