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.

A liquid crystal display device comprising:
- 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 a rear side of the liquid crystal panel, for irradiating the liquid crystal panel with white light;
- and
- an absorbing layer which is provided between the backlight source and the liquid crystal cell, for absorbing only the light of a wavelength band corresponding to a changed color of the white light while passing through the liquid crystal panel in an oblique direction with respect to a normal direction of the liquid crystal panel.
A polarizing plate for a liquid crystal display device comprising:
- a polarization layer which controls polarization of incident light;
- and
- an absorbing layer which is arranged on a path of the incident light, for absorbing from the incident light, the light of a wavelength band corresponding to a changed color of the white light while passing through the liquid crystal panel in an oblique direction with respect to a normal direction of a liquid crystal panel included in the liquid crystal display device.
A backlight source for a liquid crystal display device comprising:
- a light source unit which irradiates white light;
- a scattering layer which scatters the white light;
- and
- an absorbing layer which is arranged on a path of the white light, for absorbing from the white light, the light of a wavelength band corresponding to a changed color of the white light while passing through a liquid crystal panel in an oblique direction with respect to a normal direction of a liquid crystal panel included in the liquid crystal display device.
