Liquid crystal display device comprising color polarizing plate

Image Number 3 for United States Patent #8149355.

A liquid crystal display device includes a pair of substrates, electrodes formed on the opposing surfaces of the pair of substrates, and a liquid crystal layer twisted in the gap between the pair of substrates at a predetermined twisted angle. A normal polarizing plate to exhibit a polarizing function for the whole visible light is arranged on the outer surface of an observation side substrate in the pair of substrates. A color polarizing plate to exhibit a polarizing function for visible light of a wavelength band other than a specific wavelength band is arranged on the outer surface of the opposite side substrate in the pair of substrates. A reflecting plate to reflect light entering from the observation side toward the observation side is arranged on a surface of the color polarizing plate that is opposite to the surface that opposes the opposite side substrate.
