Abstract:
A liquid crystal display device according to the present invention includes a liquid crystal panel which has a liquid crystal cell including a predetermined liquid crystal layer and polarizing plates for holding the liquid crystal cell, a backlight source which is arranged on the rear side of the liquid crystal panel, for irradiating the liquid crystal panel with white light, and an absorbing layer which is arranged between the backlight source and the liquid crystal cell, for absorbing only the light of the wavelength band corresponding to a changed color of the white light while passing through the liquid crystal panel in the oblique direction with respect to the normal direction of the liquid crystal panel.
