ABSTRACT:
Optical compensation elements include first phase plates and second phase plates, which have retardation in a front-plane direction. When a value Δn/Δnλis set by normalizing a retardation amount Δn·d relating to light of each of wavelengths by a retardation amount Δnλ·d relating to light of a predetermined wavelength λ, a normalized value Δn/Δnλin the first phase plate is greater than a normalized value Δn/Δnλin a liquid crystal layer, and a normalized value Δn/Δnλin the second phase plate is less than the normalized value Δn/Δnλin the liquid crystal layer, with respect to light of wavelengths other than the predetermined wavelength.
