Liquid crystal display device

摘要

Optical compensation elements include first phase plates and second phase plates, which have retardation in a thickness direction. When a value Deltan/Deltan_lambda is set by normalizing a retardation amount Deltan.d relating to light of each of wavelengths by a retardation amount Deltan_lambda.d relating to light of a predetermined wavelength lambda, a normalized value Deltan/Deltan_lambda in the first phase plate is less than a normalized value Deltan/Deltan_lambda in a liquid crystal layer, and a normalized value Deltan/Deltan_lambda in the second phase plate is greater than the normalized value Deltan/Deltan_lambda in the liquid crystal layer, with respect to light of wavelengths other than the predetermined wavelength.
