Abstract:
1. A reflection type color liquid crystal display device for displaying a color image formed based on unit pixels each comprising sub-pixels corresponding to primary colors by using extraneous light, which comprises: a liquid crystal layer varying a state of light transmitted therethrough in accordance with electric field applied thereacross; a reflection layer reflecting light which is incident thereon via the liquid crystal layer; transparent electrode layer and pixel electrode layer for applying electric field to the liquid crystal layer for each of the sub-pixels in accordance with an image to be displayed, the transparent layer located on a side of one main surface of the liquid crystal layer on which extraneous light is incident, the pixel electrode layer located on a side of another surface of the liquid crystal layer on which light reflected from the reflection layer is incident; and a color filter layer being divided into at least two portions, each portion in correspondence with the subpixels and having an appropriate optical filter part for coloring (or transmitting all light components), wherein at least one portion performs coloring for the primary colors and at least one additional portion filters or transmits light components of predetermined wavelengths, wherein the at least one additional portion is integrated with a light scattering film, wherein the at least one additional portion and the light scattering film are integrally formed from the same material.
