Abstract
In a display device which includes: a first substrate; a second substrate; and a thin film polarizer which is directly formed on a surface of the second substrate on a side opposite to the first substrate, the thin film polarizer includes a polarization element film and a protection layer which is laminated to the polarization element film, the polarization element film is made of an aligned lyotropic liquid crystal material, and the protection layer has a refractive index smaller than a refractive index of the polarization element film in a transmission axis direction. The protection layer may have a thickness smaller than a thickness of polarization element film.
