(57) [Summary] [Problem] To increase the number of complicated steps such as a photoresist step or to require an advanced bonding technique, Provided is a bright liquid crystal display device having high contrast and capable of easily switching between a wide viewing angle and a narrow viewing angle. Further, in such a liquid crystal display device, there is provided a liquid crystal display device in which occurrence of color unevenness is suppressed and deterioration due to light is suppressed. SOLUTION: A color filter layer 105 composed of at least one cholesteric liquid crystal layer is arranged inside a liquid crystal cell. As a result, alignment with the wiring for driving the liquid crystal and the like becomes very easy, and a high aperture ratio can be achieved. Further, switching between a wide viewing angle and a narrow viewing angle can be easily performed by attaching / detaching the scattering film 207 or turning on / off the polymer-dispersed liquid crystal 307, and there is no need to define the alignment direction of the liquid crystal. Therefore, the liquid crystal mode that switches at a high speed can be used freely. Furthermore, since light that has been conventionally cut off by a polarizing plate can also be effectively used, a bright display is possible, and unlike a conventional color filter, light is not absorbed, so that deterioration due to light can be suppressed. |
