  • Publication number: 20060197896
    Abstract: A color filter substrate includes a substrate and color layers of different colors which are disposed on the substrate. The color layers are provided in unit pixels. The unit pixels each include subpixels. The subpixels each include a reflection region where light entering the pixels is reflected and a transmission region where light entering the pixels is transmitted. The reflection and transmission regions include a different combination of two color layers selected from the color layers for each of the subpixels. The two color layers are adjacent to each other in a plane in the reflection region and are stacked on top of each other in the transmission region. The transmission region of at least one of the subpixels has an unstacked area where one of the two color layers is formed.
