Abstract:
1. A display device comprising: a first substrate; a second substrate; a first polarization element film which is formed on a surface of the second substrate on a side opposite to a side where the first substrate is arranged; and a first protection 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, wherein the first polarization element film is made of an aligned lyotropic liquid crystal material, 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, (n the thickness of the first protection layer is at least 60 nm and no greater than 190 nm.
