ABSTRACT:
In a transflective type IPS type liquid crystal display device in which a phase difference layer has been built in a reflection display portion, a retardation value of the phase difference layer corresponding to a short wavelength color filter is different from a retardation value of the phase difference layer corresponding to a long wavelength color filter; while a blue display pixel is set to the short wavelength color filter and both red and green pixels are set to the long wavelength filter, the retardation value of the phase difference layer corresponding to the former-mentioned short wavelength color filter is made smaller than the retardation value of the phase difference layer corresponding to the latter-mentioned long wavelength color filter.
